Shuichi is pregnant with Yuki's twins, thanks to a genetic error. The secret burns him inside, so he cuts himself to stop the emotional pain. Yuki gets sick of Shuichi's white gerbil, so he shoots it. In a rage one day, Shuichi had trashed Yuki's two cars, so Yuki is forced to drive a minivan. One day, cutting isn't enough. Despite the two children growing inside of him, Suichi uses meth, cocaine, and majuana. Yuki remembers parts of his relationship with Kitazawa that he has repressed for years, other than the day he killed him, so drinks more, cuts as well, and uses crystal meth. Combination of past abuse and current substance abuses causes Yuki to contract Amnesia. Tohma learns that everyone in the Gravitation cast are drug users, so he decides to join them. After a month of drugs and self mutilation, Shuichi breaks up with Yuki, even then under the influence, claiming that the (s) was terrible. Heartbroken, remembering Shuichi, and sober, Yuki goes to family for support, but gets the wrong support. Out of rage and shock, Yuki kills Mika, Tohma, Tatsuha, and the Uesugi's father. Then he takes some weird pills that makes his rage escalate to the danger zone. He goes out for a killing spree, killing Hiro, Suguru, Sakano, and K by strangling them, Ryuichi by shooting him in the face, Noriko by shoving an empty beer bottle down her throat, Aizawa, Ken, and Maa by dragging them to the public pool and holding them under until they drowned, and his editor by kicking her into a paper shredder. He feels remorse when he realizes that Suichi will be angry with him and never forgive him. So Yuki runs out in front of a speeding truck and gets hit. Seeing Yuki get hit by a truck is the final straw for Shuichi. He goes home, takes the knife, and cuts his head off. And no one ever looked for them, because they weren't really that important anyway.
