Yuto Chikamori

Background

Chikamori was a student at Jingiin University in the Department of Mathematics and Science. At some point, he started dating one of his classmates, and took her to a fishing pond for their first date. In their third year of university, his girlfriend became devoted to solving a mysterious equation she found. She eventually became comatose two years later upon discovering the solution. Chikamori found her notebook and attempted to continue her research.↗

After three years, his girlfriend was still comatose and had not much longer to live according to the doctors. Chikamori had already graduated from university. During the university's summer break, he got hired at their library to assist at the service counter and act as the library's information guide.↗↗

Censored Equation

When Rohan Kishibe visits the university library to research extraterrestrial life for a short story, Chikamori is assigned by the library director to assist him in gathering materials. Though initially indifferent to Rohan's project, he dutifully collects a wide range of reference books, including SETI reports, astrobiology papers, and journals on the Wow! signal.↗

After Rohan finishes his research, he notices that Chikamori has left behind a notebook. Upon inspecting it, he finds a single complex equation written repeatedly across the pages, with the first page torn in half. As Rohan examines the notebook, Chikamori suddenly returns and, in an unsettling manner, recites a multilingual warning that "permission is required to view" the contents. His eyes roll back unnaturally before he regains his composure, acting as if nothing happened.↗

Chikamori reveals that the notebook originally belonged to his girlfriend. He believes solving the equation may fulfill her last wishes. He asks Rohan to incorporate the equation into his short story, hoping that wider exposure might lead to new insights. Rohan feigns interest and asks Chikamori for the hospital's location, but he is reluctant to tell Rohan. Rohan uses Heaven's Door to get the information from him.↗↗

Unaware of Rohan's deception, Chikamori later arrives at the hospital in the evening to visit his girlfriend, carrying a bouquet of yellow gerbera daisies. Due to Heaven's Door, he does not recognize Rohan when they see each other at the elevator, but he gives Rohan a small bow as Rohan lets him pass by. As he enters his girlfriend's hospital room, he is met with the shocking sight of her being awake, prompting a startled gasp just as the elevator doors close behind Rohan.↗↗
