Keiya Utou

Keiya Utou is the 26-year-old wakagashira of the yakuza organization Senagaki-gumi. To serve as a personal guardian for Kazusa, the granddaughter of his boss, he bribed school officials and concealed his true age to infiltrate as a high school student. Calm in demeanor and formidable in combat, he showers Kazusa with boundless affection and an intense drive to shield her, vowing to eliminate every male classmate he deems a nuisance—all while quietly wrestling between sworn loyalty and unspoken feelings.
