~Based off of my webcomic: Shukumei of Jinsei and Shi and it's remade version: Shukumei of Jinsei and Shi -REBIRTH-~ You play as Hisoka Misushima, a boy that ended up being involved in a game of life and death. It all started with the murder of Miyako Kurosawa... then, her death caused others to be trapped in this fate. Who is the one that murdered her... and the one that could continue their killings?
Matsuki Misushima is, as his name shows, the (older) brother of the main protagonist: Hisoka Misushima. Due to their (Hisoka and Matsuki's) appearances, they seem like they would almost be exactly the same, (Well, only when it comes to their personalities.) but, they're not.
