kosaka_shunpei
Character from Super Heroine Boy.
An insecure, mousy otaku who has a crush on Yukari. Was bullied in the past and is distrustful of Ooiwa Wataru because of his delinquent background.
Originally in posts such as post #2794427 his name was given as Konishi Shunpei, but later pages (such as post #3297586) gave his surname's pronunciation as Kosaka.
