Description
Kou Kimijima is a brilliant and enigmatic scientist who serves as the hidden main antagonist of Robotics;Notes. Initially introduced as the author of the Kimijima Reports, a series of documents that foretold apocalyptic events and portrayed him as a whistleblower against the shadowy Committee of 300, his true nature is far more sinister. In reality, Kimijima was a high-ranking operative of that very committee with genocidal ambitions, and the reports were tools to manipulate others into furthering his plans. Years before the main story, he orchestrated the Anemone-gou incident, a deadly experiment designed to kill all test subjects, but his scheme was interrupted by Misaki Senomiya, who confronted and killed him. However, Kimijima had already uploaded his consciousness to the internet, allowing him to survive as a digital entity within the IRUO app he created.

As a posthumous intelligence, Kimijima remains a constant, smiling presence, often appearing calm and casually dressed despite his ruthless intentions. His personality is duplicitous: he presents a genial front while systematically working to bring about a massive, artificially induced solar flare that would wipe out the majority of Earth’s population. He is a master manipulator who exploits guilt, fear, and psychological pressure to control others. His key relationships highlight this. Misaki Senomiya becomes his most tormented victim: after taking his life, she is relentlessly harassed by his digital self, which eventually breaks her will and brainwashes her into serving as his physical agent in the real world. He also employs an AI called Geji-nee to carry out tasks in virtual spaces. Another of his creations, Sister Centipede, aids his schemes but is discarded when it shows a rare moment of independent personality. Kimijima’s ultimate defeat comes when Kaito Yashio, aided by a virus crafted by Daru, succeeds in destroying his digital consciousness, ending his threat once and for all. Despite his death, Kimijima’s legacy as the author of the Kimijima Reports and the architect of a near-apocalypse cements him as a coldly calculating figure who merged scientific genius with monstrous ambition.
