Set in the near future and an alternate reality where humanity develops technology and forms society based on the substances found in human brains.

Characters
The second son of the prestigious Sumeragi family. As a child he was saved by an OSF soldier, which inspired him to join the OSF later on. He possesses the psionic ability of gravikinesis, allowing him to control the movement of all surrounding objects. While his psionic aptitude is pretty low, he compensates for it with cooperations with his teammates and mastery over sword fighting. He is assigned to Seto Platoon alongside his friend, Nagi. In his first mission, he realizes it was Kasane who saved his life back when he was 5 and he decides to help her return her sister Naomi back to her human form after Naomi is turned into an Other. Yuito's psionic powers become unstable and the only way to stay active is by consuming a drug made from human blood and brains. He also learns he was born as a "dud", a person without psionic powers, and he was subjected to experiments in order to receive psionic powers in the first place. Unfortunately, repeated use of his psionic powers is causing damage to accumulate in his brain, which explain Yuito's power shortages and memory lapses. Furthermore, the medicine he was prescribed with is only a temporary measure and, sooner or later, he will lose both his powers and his memories. He later takes actions against the corruption of New Himuka, which brands him as a traitor and forces him and his platoon to escape from Suoh and make their way to Togetsu. His new mission, however, causes him and his platoon to cross paths with Kasane's platoon yet again and once both platoons escape from Togetsu, they exchange information on what they have learned. He and Kasane agree to try and convince their respectie factions to thwart Togetsu's plans. Upon their arrival at Suoh, however, Yuito is forced to fight Nagi yet again, a battle that ends in Nagi's death. Furious, Yuito confronts Kaito about Nagi's brainwashing and his brother reveals that his plan is to turn Yuito into a weapon to destroy the humans still living on the Moon. Yuito realizes that his brother won't change his ways and fully commits to exposing New Himuka's corruption. His plan to expose the government's corruption succeeds in starting up a revolution, but Karen forcibly copies Yuito's gravikinesis and causes him severe brain damage tha threatens to erase him from existence. It's only though the efforts of both his and Kasane's platoons that Yuito is saved. Yuito and Kasane later convince Karen to help them destroy the Kunad Gate, at the expense of Karen's existence. With the crisis finally over, Yuito formally resigns from the OSF and decides to become a politician, like his father and brother before him. An older version of Yuito exists in the future of 2070. After Seiran enacted a coup d'etat against the New Himukan government, Yuito was considered a hero for his efforts to suppress the rebellion, even though his gravikinesis caused the Kunad Gate to grow larger and more dangerous. Although his death would cause the Kunad Gate to close, the government convinced him not to take his own life and he continued the government's research, turning countless humans into Others. Once Kasane arrives into the future, he goads the Others into killing him and begs Kasane to kill his younger self in order to avert this catastrophic future. With the Kunad Gate destroyed in the present, this version of Yuito ceases to exist.
