The twenty-two year-old student who apparently works as a part-time cameraman. Although he addresses Kanou as "nii-san" (Japanese for "older brother"), he is not related to Kanou. He loves to record AV (Adult Videos) and thought Ayase was a girl the first time they meet when Kanou calls him. Despite often getting beaten up by Kanou, he displays an incessantly friendly behavior towards him and is not afraid to taunt and tease him from time to time. He also has developped a liking for Ayase and is especially grateful to him for having mellowed Kanou's merciless and aggressive personality.

In the artbook, the most expensive thing he owns is his camera which costs about 400,000 Yen. He also dreams of recording an AV of Kanou and Ayase.
