Shinkawa Kyouji/Bio & Battles

"This won't do, Asada-san. You can't betray me. Only I can save Asada-san, so you can't look at other guys."

- Shinkawa Kyouiji to Sinon Kyouiji Shinkawa is a rare example of a male yandere character. Kyouiji is, along with his brother Shouiji, a player of the MMOFPS Gun Gale Online, and the co-owner of an avatar known as "Sterben", armed with a weapon known as the "Death Gun", a Type-54 pistol said to be able to kill players in the game in real life. In truth, one of the brothers kills the player in game, while another sneaks into the opposing player's house, located by covertly reading login data for a multiplayer tournament, and poisons them. It is later discovered that Kyouiji is obsessed with a girl named Shino Asada, and threatens to kill her and then commit suicide when she refuses his advances.
