He appears in the second part of Sensitive Pornograph. He is "supposedly" the rabbit that Ueno is supposed to be "pet-sitting" for. It turns out that Ueno finds Aki in a closet. This is a very short episode between the two boys. A mystery man videotapes Aki and Ueno having sex. After Ueno and Aki "do the deed," Ueno leaves, and Aki is left alone. Shortly after, the mystery man appears, and Aki tells him that he doesn't want to be his "pet" anymore.
