One of the Homura raid captains is known for his impulsiveness and dedication to his comrades, despite being a brash teenager with high self-esteem. He shows no hesitation when attacking his opponents, but can be vulgar and easily irritated, often cursing openly towards those who cross him. Despite this, he holds great respect for his fellow Homura members, especially Mikoto, causing him to become shy around girls. His first name is not used, as he prefers the nickname Yatagarasu (八咫烏), which reflects his sharp night vision and fierce nature. He joined HOMRA with Saruhiko when they were teenagers.
