A 20-year-old man and a manga artist who moved to Tokyo two years prior to fulfill his lifelong dream of becoming a successful manga author, but is occasionally fired from each manga magazine. He is then recruited to Comic Splash by his next door neighbor Hinata after he was fired from Comic Heat. He is revealed to be a virgin, and as a result has poor experience with women. It is revealed by Hinata in chapter 5 that Kouta is a "trigger-type" artist, an artist who can produce amazing results if something stimulates them (sexual or otherwise). This ability was first shown after Kouta saw Mika Fujiwara's breasts once, which inspired him to draw more buxom women for his manga. He was influenced to become a manga artist since childhood, and was influenced by Ozma's works.
