Yuno Gasai

Yuno Gasai is the famous yandere from Future Diary and appeared in the Fiction V. Fiction episode, Yuno Gasai vs Genocide Jack, where she fought Genocide Jack from Danganronoa.

History
Yuno was adopted by her parents at a young age. Her life was happy for several years until the strain of money began to emotionally and psychologically affect her parents. Her father stayed at work until late and barely interacted with his family and her mom began to abuse her, wanting her to become the "perfect citizen," eventually locking her in a cage and timing everything she did, from sleeping to eating. Yuno's mother went to the extreme, leaving her to starve and when she did feed her, she was force-feeding her inedible materials. While her father objected to his wife's severe treatment of Yuno, he did little to nothing to stop her. Eventually and understandably, Yuno snapped and managed to imprison her parents and let them starve to death. Bills couldn't be payed for and the house turned to shit, making Yuno fall into despair. Life was miserable for Yuno until she found Yukiteru, falling in love with him. Her cell phone given to her by some loli started to tell her what Yuki's actions will be because she started to stalk him. Then The God known as Deus gave her the opportunity to become a God, I described the format earlier, and when she agreed, her phone became a Future Diary. After learning that Yuki is in the competition, they joined together in this battle royal.
