Censored Equation

"Perhaps an artificial intelligence with free will can safely solve that equation. In any case, that equation is still something that mankind shouldn't mess with."

- Rohan Kishibe

Summary
Rohan was asked by Shueisha to write a short story on the theme of encountering the unknown, and so he visits a university library near Morioh to find out about aliens. Yuto Chikamori (近森 優斗), a graduate student, assists Rohan in finding documents because he was Rohan's fan. However, Rohan was interested in Chikamori's notebook that was placed on the desk. Rohan finds a partially torn page with a mathematical formula on it. When asking Chikamori about it, the student reacts strangely and reveals that it was a fragment of a mathematical formula to interfere with another dimension. It is said that his girlfriend became unconscious in the middle of trying to solve it.

Assuming the cause of his girlfriend's state was due to the equation, Chikamori attempted to solve it but could not do so due to it being incomplete. Since his girlfriend had little time left to live, Chikamori pleads with Rohan to use this in his short story to bring attention to it and find any clues. Rohan becomes curious about his story and goes to the hospital where Chikamori's lover was hospitalized to find out the truth.
