Scarlet Nexus is a Japanese anime television series adaptation of the video game of the same name. It is produced by Sunrise (now Bandai Namco Filmworks) and aired from July to December 2021.


Set in the near future and an alternate reality where humanity develops technology and forms society based on the substances found in human brains. These substances also grant humans extrasensory superpowers. The Other Suppression Force (OSF) recruits members with supernatural abilities to protect humanity from the Others, mindless mutants descending from the Extinction Belt.[1]


Yuito Sumeragi (ユイト・スメラギ)
Voiced by: Junya Enoki[2] (Japanese); Chris Hackney[3] (English)
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 respective 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.

She is the adopted child of the prestigious Randall family and the younger sister of Naomi, whom Kasane protects with the utmost dedication. Upon graduating, she and Naomi are assigned to the OSF's Kyoka Platoon. Through unknown circumstances, she saved Yuito's life back when he was 5, inspiring him to join the OSF. Over the course of her life, she has been haunted by dreams about a mysterious voice telling her to hold on to the red strings. In the present, she doesn't immediately trust Yuito and attempts to fight him personally to verify if he's worthy of Naomi's love. Unfortunately, during a mission to hunt Others down, Naomi is turned into an Other and forcibly taken away by the group Seiran. When Naomi is officially declared killed in action, Kasane is disowned by her family for her failure to protect Naomi. Even so, Kasane decides to find a way to turn Naomi back into a human. Her latent power of gravikinesis takes her into the dark future of the year 2070, where she meets an older version of Yuito, who reveals the truth about Kasane's powers and begs her to kill his past self in order to avert this dark future from coming to pass. Upon returning to the present, Kasane is drafted into Seiran after Karen promises to find a way to return Naomi to her human form. Unfortunately, she still struggles with the task of killing Yuito and she later discovers that Naomi is only capable of human communication if she consumes a drug made from human blood and brains. She and her group ultimately decide to travel to Togetsu, an independent city outside the jurisdictions of both New Himuka and Seiran, to find a way to save Naomi. Once they reach the entrance, the denizens of Togetsu tell Kasane that she was born on Togetsu and the story of her parents being killed by Others was a fabrication by New Himuka in order to harvest her psionic power. Unfortunately, she is captured by Togetsu forces and through a dream, she discovers that she herself is actually one of many Design Children genetically engineered by Togetsu in order to harness the red strings of time and space. Once Yuito's platoon reaches Togetsu, however, both platoons help each other escape and once they reach a shelter, they exchange information on what they have learned. She and Yuito agree to convince their governments to thwart Togetsu's plans, but she is later forced to endure Naomi's death. She later discovers that she and Yuito share the same mother, Wakana Sumeragi, who helps them shut down the Kunad Gate at the cost of her own life. With the Kunad Gate finally closed, Kasane joins a space project to explore the moon.
