Appearance in Midori no HibiShuichi Takamizawa, a character in Midori no Hibi, loves a Magical Girl show named "Ultra Marin". He is a doll otaku and always carries around a doll of Ultra Marin, and seems to have a creepy obsession with the character (even having a crush on a girl because of her similarity, but lost interest when she is shown to be tough rather than innocent).
