Appears in "Facehugger," "Animal Magnetism Theory," and "Lovesick Rappart."

He is a classmate of both Kiyosubashi and Kototoi. He is also the object of their affections. He had seen movies from the "Alien" series, citing "Alien 3" as his favorite. He went searching for the "facehugger" with Kiyosubashi because he didn't have any reason not to. This made her call him a "good person."

In "Animal Magnetism Theory," she was going out with Kototoi but was initially keeping their relationship a secret. He allows Kiyosubashi to order him around partly due to guilt, blaming himself for the loss of her hand.
