Issei vs Tatsumi

Issei vs Tatsumi is the tenth episode of Fiction V. Fiction, featuring Issei from Highschool DxD and Tatsumi from Akame ga Kill.

Interlude
A harem is when many girls wants one guy. A dragon is a giant awesome lizard. And a basic looking protagonist is the main character that anyone can portray themselves as. Today we'll be looking at two characters that fit all three descriptions and lived a life that they never expected to have.

Issei Hyoudou

Rias' perverted Red Dragon Emperor from Highschool DxD.

And

Tatsumi

Night Raid's dragon armored assassin from Akame ga Kill.

I'm Aipom and today I'm here to determine who between these two characters could win a match of Fiction V. Fiction

Issei
(Cue: Highschool DxD Opening 1)

Before Issei's birth, his mother was pregnant twice but with both ending in miscarriages. So when the first kid was successful, the parents named him Issei, meaning "honesty". Sometime during his childhood, he met an old man who told him other children stories about boobs, which should put him on a watch list. But this eventually led to Issei's fascination with them and his perverted tendencies. This is likely what led him to attend Kuoh Academy, a school where nearly all the students are girls. This perverted virgin was desperate to get his dick wet with a girl, and that's when a girl named Raynare asked him on a date. But it turned out Raynare was a fallen angel and was planning to kill Issei. The reason was because Issei had some dragon weapon called a Boosted Gear in his arm and that was a threat to her kind. And she succeeded in killing him, only for a demon called Rias Gremory to revive him as a demon, and her pawn on the chest board. So Issei went from a normal pervert to a demon with a dragon arm. With the new goal to become a harem king as well.

This combination of a Boosted Gear and demon rebirth is a great combination with power. Boosted Gear is a Sacred Gear, which are items with powerful abilities bestowed upon humans by God of the bible. They can do things like heal, change appearances, create items, focus on defense, use elements, ect.

Boosted Gear is a change state gear, which changes appearance with dragon armor. Boosted Gear holds the Spirit of the Welsh Dragon Ddraig, who was one of the two Heavenly Dragons. It's also one of the 13 Longinuses, which means it's super charged and one of the strongest. It enables Issei double the power every 10 seconds and becomes more powerful based on the Issei's strong emotions because this is anime. It can also transfer to another being or object. And to unleash all the boosted power into a move, explosion will release it all. It also has some special moves, like the next listed moves.

Dragon Shot - where it fires a beam of energy or ball of energy at the opponent, but the ball can home in on opponents.

Dress Break - strips people of clothes by touching them and clicking fingers, but only used on girls and you're old enough, I don't need to explain why.

Pilingual - enables the user to communicate with the target's breast, allowing Issei to predict the target's next move and it's also a move only used on girls.

Flame Blaze - where Issei fires a stream of dragon flames from his mouth.

After making a deal with Ddraig, he was able to upgrade to Boosted Gear: Scale Mail. It upgrades the Boosted Gear gauntlet to a full suit of armor, giving him more attacks and a huge boost in durability, speed, and strength. There's a good few of these upgrades and definitely a good amount of new attacks, which we're gonna list the Scale Mail attacks now.

Dividing Wyvern Fairy - Creates white wyverns that can "Divide" and "Reflect" attacks. They can also turn red, which allows the wyverns to "Boost" and "Transfer" instead. Formerly a gauntlet infused with one of Divine Dividing's jewls, allowing the user to half the power of an attack, however costing half of the user's life spawn.

Juggernaut Drive - Temporarily removes the seal on the Heavenly Dragon in the Boosted Gear and grants Issei immense power, at the coast of his sanity. Though Issei has only entered an incomplete state of Juggernaut Drive.

Longinus Smasher - A powerful energy beam fired from the helm of the Scale Mail, and also the most powerful attack in the Booster Gear's arsenal.

Illegal Move Triana - Changes Issei's Scale Mail depending on the Evil Piece the user is promoted to.

Welsh Sonic Boost Knight - Sheds excess armor to increase speed

Welsh Dragonic Rook - Increases power and defense at the cost of maneuverability. It has a finisher move called "Solid Impact", a punch that increases power and speed by nailing percussion hammer on the elbow.

Welsh Blaster Bishop - Issei is granted an enormous amount of magical energy which us fired from the cannons that back due to the transformation. It also has a finisher called "Dragon Blaster", which is a more powerful version of Dragon Shot and can briefly warp space and time.

Cardinal Crimson Promotion - The queen promotion. This has all three Evil Piece traits, making it the most balanced and most powerful form of the Scale Mail. Enables the use of enhanced versions of the Illegal Move Triana. It's also known as "True Queen".

Solid Impact Booster - By morphing one of the armor gauntlets into Welsh Dragonic Rook's, it allows it for an enhanced version of Solid Impact. It can also be used in tandem with Ascalon to deal further damage to dragons.

Penetrate - Allows Issei to bypass any defensive abilities or abilities that would prevent his attacks from hitting. It can also be transferred to other parts of the body.

And sense we brought up Scale Mail, there's a move he can use without the armor being involved called Nyuutron Beam Cannon. It gives him the ability to attach Scale Mail's tail to a girl's breast and absorb their boob's energy. This allows a powerful beam cannon to be fired from the energy being infused with Issei's demonic energy. As a bonus, the girl's bust size is displayed in his gauntlet's jewl and the number determines how powerful the beam will be. By using Rossweisse's breast, which size is a wopping 96, he was able to launch an attack comparable with Infinity Blaster. It's strong enough to defeat the strongest Grim Reaper, Thanatos.

Then there's another form called Diabolos Dragon, a variant of the True Queen unlocked by using the power gained Ophis. It is the only one who can use it due to his body being created by Ophis' power and Great Red's flesh. It gives Issei an extra pair of wings and a finishing move known as Infinity Blaster. It overwhelmed the Sacred Gear Canceller, which nullifies other Sacred Gears. It can also use a less powerful version of Canceller called Pseudo DxD for 88 minutes. But this form can only be maintained for a short amount of time and leaves Issei in unbelievable amount of pain after use.

And then there's Ascalon, a holy sword given to him that he can wield and merge with his Boosted Gear, which is weird that a demon has a holy sword because it's a holy item but whatever works. Ascalon is able to channel the Dragon Slayer power to his punches and the sword can spawn from his Booster Gear, making it a convenient summon. Ascalon also has other models, being Ascalon II and a prototype of Ascalon II. The prototype he fused with the tail of his armor to act more as a third arm and Ascalon II is basically the same as the original, but with it releasing a holy aura. But he has learn to use the original Ascalon in more ways, endowing it with Penetrate and Boost, as well as being able to launch it as a projectile and harm dragons.

You think we're done with forms and abilities with this man? Well strap in because now we have Diabolos Dragon God. This form is from him borrowing Ophis' power. The Scale Mail enhances from here with a nice color change to crimson and black and another pair of wings. Boost has been changed to D∞D as Issei powers up ane ∞ appearing on all the gems on the armor. This form can only be held for so long and it gives him more pain than death. This was also updated to Pseudo-Dragon Deification, which can only be held onto for 88 minutes, and then the form got another upgrade to True-Dragon Deification which is described to have the aura of a devil, dragon, and god. Confused yet? Well good because next we have the abilities behind this turducken of a suit.

Infinite Blaster - The wings shoot out powerful blasts of red and black aura

Longinus Smasher - A blast that can annihilate almost anything in it's path

Blazing Inferno of Scorching Flames - A blast of fire that will continuesly burn through anything, likely even the soul until there's nothing left, as well as being able to cover an island

Red Dragon Emperor Ddraig Manifestation - Due to a drug he drunk, this attack lets him summon Ddraig into battle after the countdown on his gauntlet reaches 0

Dress Break DxD - Being able to halt the movement of any female opponents and destroy their clothing without touching them

And then there's his Apocalypse AnswerArms. This is Issei's AxA form, which is caused by combining himself with his familiar, Ryuuteimaru, which apparently makes him into a giant fucking flying robot. This form is so great that it overwhelms a Primordial God in Greek mythology called Tartarus. It has the destructive power to destroy the whole world. The drawback to this form is that it leaves Ryuuteimaru unable to move for a few days as a toy boat and gives Issei severe fatigue for a few days. But what's a little fatigue for more new abilities and built in weapons.

Revelation Barrier - Creates a strong barrier around his body and is powerful enough to withstand attacks from gods

Revelation Blade - When 4 arms on Apocalypse AnswerArm form, each arm carries a blade of their aura known as Apocalypse Ascalon, which cam easily cut through a god's tentacles.

Revelation All-Range Blaster - Apocalypse AnswerArms has several cannons to fire powerful blasts of aura that can destroy a God's magic barrier like paper and almost all of Tartarus' body, even as Issei held back his power. The blast itself can alter the environment without issue and destroyed the artificial space.

Oh yeah, his left arm has Dragonfication, which means that it's permanently in the Scale Mail form due to a sacrifice and can't be hurt by holy weapons sense it's a dragon arm. He's found how to do that with his whole body in his base form. Thought I should say that.

He can promote from the the chest pieces like pawn, rook, knight, bishop, and queen. He has enhanced stamina and senses, immense strength and durability, master at hand-to-hand combat, can turn any part of his body into that of a dragon, has developed survival skills, extreme fire resistance (only fire from Dragon Kings and the Phenex Clan have affected him), is able to mask his presence from others like a ninja, has demonic powers to cast spells, can talk to any sentient being, and can summon Ryuuteimaru at any time.

He's punched Raynare through a wall, powerful enough to destroy a mountain, stated to possess the power of a High-class devil, fought on par with Riser Phenex, obliterated a replication of Kyoto, usually destroys mountains and islands with Juggernaut Drive, can match characters that can demolish mountains and rivers, and Apocalypse AnswerArms can destroy planents and the environment. He's climbed a steep mountain with a large rock and Rias attached to his back and sliced Tartarus' arms off.

He's dodged attacks from Barakiel (who's kept with Viel, who has dodged light), blitzed Keisha (who can dodge lightning), tore Shalba Beelzebub's flesh before he could react, has dodged lightning, and managed to evade attacks from Tartarus.

Casually withstood casual attacks from Balance Breaker Vail (who annihilated a mountain range), can withstand attacks from Balance Breaker Sairaorg, managed to withstand Vidar's Fimbulvetr Shot, and tanked all of Tartarus's attacks without a scratch.

He's continued to fight with fractured arms and crushed arms and could temporarily endure the sensation of Raynare's light burning up and melting his insides. And he's a skilled tactician, leading some fights and can exploit other's weaknesses. And he's fought a high variety of foes, from other chess pieces and other Gods. And he's not afraid to fight dirty with girls, like a true man.

Though he's far from perfect. Some of his attacks only work on girls, and way too many of his attacks takes too much stamina. And his forms all have a very small time limit. And he's extremely perverted, and can easily be distracted by the vicious beast known as boobs!

Issei did eventually get with Rias, and Akeno, and Koneko- he ended up trying to marry 8 girls. Rias is though his top girl. He had the dream to become the harem king and it seems he's made that dream come true. On the plus, he also became a beloved kids show character called the Grabbin' Dragon where he sings about boobs... What the hell is this show?

(Cue: Highschool DxD Issei)

Tatsumi
(Cue: Akame ga Kill OP 2 Liar Mask)

Imagine a world where the government rules all. And when I say that, I mean literally. In this world, the government rules with an iron fist, and the rich can do as they please to anyone lower than them. Whether to pick them up and use them as prostitutes, to kill them for accidentally bumping into them, or to just simply torture them for fun. Most are terrified of the rich and the government for this reason, but there are some people willing to fight back against them. To get their hands dirty and to take out these power abusers. This is where the assassins for hire come in known as Night Raid! This group's goal is to take down the Empire, take down the government and the rich! And one of Night Raid's strongest members comes from a simple, small village. Tatsumi!

Tatsumi grew up in a small and poor village and wanted to become a soldier in order to try helping his village. After he finished his training, him and his two friends, Saya and Ieyasu, went to the Empire to join the army and make their way up, naive to the truth. Though Tatsumi got separated from Saya and Ieyasu along the way, Tatsumi made his way to the city and then got dejected from the army before getting scammed by a blonde cat lady named Leone. Broke, rejected, and alone, he understandablely felt bad. Until a rich, kind girl named Aria invited her to stay at her place. Things finally started to seem like they were going up until the next night, where the feared assassin group called Night Raid slaughtered the innocent Aria's family and body guards brutally. Oh, but why would they kill such a kind, innocent girl? Well surprise surprise, she actually takes in people on the street and poisons them before brutally torturing them for her own enjoyment! And two people she tortured was Saya and Ieyasu- Fuck this guy's luck is horrible! Well, understandably pissed off, after learning that Aria killed his friends, Tatsumi cut that bitch in half with no mercy! And remember that Leone who stole Tatsumi's money? Well, she's part of Night Raid and after he killed Aria with no hesitation, she offered him to join them, and he accepted. Which probably was better for him because if he didn't, they likely would've silenced him to keep him quite.

You probably aren't asking yourselves on what weapons Night Raid use to kill these higher ups. Well just like the Empire, they use special weapons called Teigu. The creation of these weapons was originally to stop the Empire from falling and can only be held by the strongest warriors. There was 48 originally made, but half has been lost and some has been broken before in combat, leaving a very few amount of Teigu left. They can range from something as simple as an axe and a giant pair of scissors to string, a flute, and a transforming dog. Everyone in Night Raid had one and there was no way for Tatsumi to keep up with a regular ol' sword. And after the death of one of the Night Raid member's, Bulat, Tatsumi took the mantle of using his Teigu, Incursio.

When Incursio is not in use, it takes the form of a sword so it's easy to carry. But when active, it turnd into armor that was made by the corpse of a dragon danger beast known as Tyrant, who's flesh is still alive within Incursio. Due to this, Incursio can adapt and evolve, gaining several abilities and upgrades. Due to Incursio being a full body-armor Teigu, it has a near-indestructible defense, with other Teigu being the only thing to be able to pierce it. Incursio also has a long spear called Neuntote when in the armor form, which can cut through Danger Beasts with ease. It also has a trump card, invisibility. Incursio can turn invisible for a certain amount of time, masking its visibility to the naked eye. Though this doesn't hide his presence, so skilled opponents can still sense him.

Incursio's most notable feature though is definitely it's evolution. After transferring to Tatsumi, it lost some of it's bulk from Bulat to be able to work with Tatsumi's agile form. Incursio can manifest the head of Tyrant from any point on the armor to protect Tatsumi from bladed weapons, protecting him from blows like decapitation. And overtime in battle Incursio has greatly enhanced it's speed, strength, and agility.

The first upgrade for Incursio was Evolved Incursio, I know it's original. This form of Incursio has a more dragon look, with sharp claws and enhanced speed and strength. This form allows him to take on foes like his crazy dominatrix stalker Esdeath and the powerhouse Budo. Evolved Incursio can even withstand Esdeath's ice and her literal time freeze. Though this did start to cause Incursio to fuse with Tatsumi's body, turning his right eye into Tyrant's.

And thanks to a fight with Shikoutazer, Incursio evolved into Evolved Incursio 2, yet again gaining speed and strength, but as well as regenerative capabilities and wings that can be used to fly. Though this updated version of Incursio caused half of Tatsumi's face to become more dragon-like with scales, fangs, a massive horn, and his hand becoming scaly and clawed.

Tatsumi got another evolution and you can guess what it's called. Evolved Incursio 3. Really scraping the barrel there, huh? Well, this one makes Incursio bulkier and giving it enough power to damage the Ultimate Teigu, Shikoutazer, which towers over the Empire. Tatsumi fused with Tyrant even more as well in this state, with horns growing from both sides of his head and his hands becoming more reptilian.

And then there's, wait for it, Evolved Incursio 4! Couldn't pick another name? Well, it's the final evolution for Incursio, which he used to destroy Shikoutazer once and for all, as well as survive hits from it that destroyed parts of the city. Though in this state, Tatsumi lost control of himself several times while in this form, with Tyrant fusing enough with Tatsumi to consider him no longer human. Loosing all humanoid traits, having his body covered in scales, his mouth forming into a dragon, and his teeth becoming jagged and sharp. Though don't worry, by remembering Bulat and his friends, he was able to take control of the evolution and take down Shikoutazer in two hits and his strength being able to rival Esdeath's, who covered a whole continent with snow.

But then there's a stage that doesn't involve evolving Incursio, being Tyrant himself. After needing to force Incursio to evolve so much in such a short amount of time to defeat Shikoutazer, Tatsumi was completely consumed by Incursio, transforming him into Tyrant reborn. Tyrant is in the Super Class, which is the strongest class of Danger Beast, being as tall as a building and being an armored dragon with the added wings and tail. But his friend, Akame, was able to kill Tyrant's mind by cutting it with her sword so Tatsumi could regain control of himself. So that's no fun.

But with the Incursio evolutions, you can believe he's one tough son of a bitch. He has killed an Earth Dragon before meeting Night Raid, breaks through a fortress wall by running through it, held up against people like Akame and Zanku before he had Incursio, shattered a boulder with one punch, is able to redirect an attack from Shikoutazer, can trade blows with Esdeath, killed Nyau with one punch, staggered the Shikoutazer with a punch, and can create shockwaves that can destroy Esdeath's ice constructs.

He's fast enough to land a punch on Esdeath, blitzed Cosmina, dodged Seryu's explosion and bullets while carrying Mine, can dodge lightning, and managed to weave around multiple supreme beams from Shikoutazer when he was in Evolved Incursio 4.

He's taken blows from Esdeath, tanked Boris' flamethrower attacks, can survive lightning strikes and energy blasts, survived a building collapsing on him, and survived one of Shikoutazer's energy blasts (which is worth 913.27 teratons of TNT).

He's defeated Captain Ogre, won Esdeath's tournament without any weapons or Incursio, defeated the Apeman with his bare hands, taken on some of the Empire's greatest fighters, has received training from the other Night Raid members, fights on pare with Akame, and was able to destroy Shikoutazer by forcing himself to evolve 3 times.

Though Tatsumi is not flawless. His invisibility has a limit and he tends to fight without much strategy. And if he forces Incursio to evolve past 4, Tyrant will take over completely and causes him to fight like a wild animal. A wild animal that is called one of the most dangerous beasts out there but a wild animal nonetheless.

Though with the loss of his two friends from the start and some of the Night Raid members, him and the remaining Night Raid members were able to take down the Empire and despite Esdeath falling for him and Akame getting close to him, Tatsumi ended up marrying the tsundere, Mine. He is stuck in the form of Tyrant though but Mine still accepts him all the same. So does that mean she's into danger beastial-

(Cue: Akame ga Kill - Tatsumi's Snese)

Fight
(Cue: Akame ga Kill ost 03 Kinpaku)

(Tatsumi and Mine are running through the streets, chasing someone)

Mine: Nice job on letting them get away!

Tatsumi: I didn't mean to!

Mine: Stop right there!

(The guy turns the corner as Issei comes to and notices them)

(But Issei grabs the blade and headbutts Tatsumi before punching him back)

Issei: Balance Breaker Boosted Gear, Scale Mail!

(Boosted Gear expands from Issei's hand until engulfing his body and turning into the suit of armor, Scale Mail)

Tatsumi: So it's like Incursio.

Issei: Explosion!

(Issei makes an orb of energt and quickly punches it, sending a blast of energy towards Tatsumi that engulfs him)

(Meanwhile. Outside of the city, Mine shoots the man they were chasing earlier)

(An explosion from where Issei and Tatsumi were fighting cuts her off and she quickly turns towards it, startled)

Mine: Tatsumi!

(She chases after where the explosion happened, cutting back to Issei and Tatsumi)

(Cue: Highschool DxD OST (CD 2) - 23 - Kettou)

(The blast destroyed several houses and leaves a cloud of smoke)

(Tatsumi grabs Issei as they clash and throws him, as they both land on separate rooftops)

(They jump from roof to roof, chasing each other down)

(This continues until they reach near a school and Tatsumi jumps towards Issei and rams his spear into Issei's stomach, with the two crashing onto a school's track field)

(Tatsumi gets up as Issei slowly gets up, with Tatsumi punching Issei across the field)

(Tatsumi stands up straight as Issei starts to get back up after hitting a gym's storage room)

Tatsumi: Give it up! You're no match for Incursio, and I rather not kill you over a misunderstanding!

Issei: Okay, maybe not like this. Ddraig, allow me to use Juggernaut Drive.

Ddraig: Are you sure?

Issei: Yeah! I can handle it. Plus, no way in hell I'm not losing to this dick!

Ddraig: If you say so. Juggernaut Drive!

(The Scale Mail starts to transform, looking more and more like a dragon while Ddraig constantly says "Boost")

K.O!

Well then. The power of friendship is usually what saves lives, but in this case, it's what killed Tatsumi.

This was an interesting matchup. Both the combatants are skilled fighters and could take a win. Incursio's ability to evolve could always keep Tatsumi ahead in the battle, but the Grabbin' Dragon had plenty of advantages to give him the win.

First let's start with their strength. Issei can match other characters that can regularly destroy mountains, and he completely destroyed an area during his freakout in Juggernaut Drive. Tatsumi was able take on the Shikoutazer and even break through it's attacks, which made a massive crator in the Republic. Tatsumi was even able to destroy it's torso. The Shikotazer is likely the size of your average mountain, making them have quite similar strength. Though the Apocalypse AnswerArms is said to be capable of destroying a planet and with True-Dragon Deification, he could cover an island with Blazing Inferno of Scorching Flames. While Issei never actually destroyed a planet, he has shown to have the capability with Apocalypse AnswerArms with one attack at full power, giving Issei that strength advantage.

Speed is a different story. Both are capable of dodging lighting, but they are both faster. Issei can match characters that can dodge light and Tatsumi can weave through the Shikotazer's supreme beams. Assuming these supreme beams are comparable to lasers, we can compare these speeds. Light travels at 670,616,640 mph and lasers travel at 1,079,252,848,800 mph. That makes Tatsumi 1609.34 times faster that Issei, giving Tatsumi the edge in speed.

Durability is another thing. Issei is capable of taking blows from people who regularly destroy mountains and Tatsumi survived the supreme beam from the Shikotazer. The beam is worth 913.27 teratons of TNT. It usually takes 20,000 million tonnes of TNT to destroy a mountain. Converting Tatsumi's feat to tonnes, the Shikotazer's beam is worth 913,000,000,000,000 tonnes of TNT. That means Tatsumi's durability is 45,650 times higher than Issei's.

Though this is where things lean more to Issei. First let's cover their intelligence. They usually don't come off the brightest but believe it or not, Issei is smarter, or at least in combat. Tatsumi is far from a strategist and goes in with his guns blazing and while Issei usually does the same, he has found his enemies weaknesses and how to use them, like in his fight against Rias. Record, they both are pretty big idiots and Issei thinks with his second head more than the one on his neck, but Issei more often wins his fights with his own ideas than Tatsumi does, with him more relying on the intelligence of his comrades like Akame and Leone.

And with experience, this leans more to Issei. They both fight beings higher than them, though Issei fights a bigger variety of enemies. Issei normally fights gods while Tatsumi fights people who call themselves gods. Let's take a look at who they fight. Tatsumi usually goes up against other Teigu welders and works with them, like the Night Raid members and the opposite Night Raid group founded by Esdeath. Speaking of, he does fight Esdeath and as well work with her, like when they were both stranded on an island. While Issei works with devils and an angel normally, as well as fallen angels in some occasions. And he usually fights people who are actual gods and even the White Dragon. And Issei fights much more foes than Tatsumi does, sometimes several at once. This gives Issei the advantage in experience.

Lastly is their arsenals. While Dress Break and the breast reading is useless on Tatsumi, he has more than those. Tatsumi just has the spear and claws, based on the evolved Incursio. Issei has far more than Tatsumi does up his sleeves. With Boost, Issei can constantly power up and he can also promote himself from chest pieces to unlock more abilities. He has plenty of attacks and while in the Akame ga Kill universe, only other Teigu could harm Tatsumi, Sacred Gears are made by gods while the Teigu is made by humans, and there's no evidence to say that anything that could be stronger than a Teigu could pierce Incursio. And with Boosted Gear being able to upgrade to forms that can demolish the environment, it can be safe to say that the Boosted Gear could break through Incursio's durability. Though let's give the benefit of the doubt and say that Incursio can survive anything that the Boosted Gear could throw at it. Blazing Inferno of Scorching Flames could possibly burn through sense it can burn through anything, but Penetrate bypasses durability. Making it safe to say that Issei could break through Incursio's defenses.

While Tatsumi has the durability and the speed to hold up a fight. Issei has the strength, combat smarts, the experience, and the far larger arsenal to put down Tatsumi for good.

Issei just had the AnswerArms to dress break through Incursio, with Tatsumi not having a way to Grabbin' a solid victory.

The winner is Issei!

Trivia

 * The connections between Issei and Tatsumi are that they are both harem protagonists with armor made of dragons that they revieced/unlocked after a death (Issei got Ddraig after dying and Tatsumi got Incursio after Bulat died).

They also both become part of their armor, with Ddraig being part of Issei's hand and Tatsumi becoming one with Incursio by the end of the series.
