Kyoushiro is a supporting character in the anime Innocent Venus, depicted as a male teenager with short white hair and gray eyes. His name is derived from a Japanese word meaning "dying insane," which aligns with his dangerous and unstable demeanor. He displays a strong fixation on knives, frequently licking them with an abnormally long tongue. Kyoushiro is a highly proficient knife thrower, capable of functioning as a silent killer at mid-range. He demonstrates these skills during an infiltration mission, where he also exhibits a clear enjoyment of causing pain while interrogating targets, and he cleans his blade by licking it after each kill. His role in the story is that of an antagonist operative aligned with the military organization Phantom. Beyond these traits, no further background, motivations, key relationships, or character development are documented in available reliable sources.
