Kazutora Hanemiya is a fifteen-year-old boy from Shibuya, Tokyo, Japan, and a member of the Valhalla gang. He rarely shows emotion, usually maintaining a calm and unreadable expression that makes it difficult for others to understand what he is thinking. Despite his detached demeanor, he is considered handsome and is quite popular at school. Kazutora is of average height with a slender build, standing at 175 cm tall and weighing 60 kg. His naturally black hair is styled in a messy wolf cut, accented with distinctive blonde streaks. He has sand-colored eyes and a small mole beneath the corner of his right eye. A tiger tattoo stretches from his neck across his shoulder and chest, adding to his intimidating appearance. He also wears a long dangle earring with a small bell attached to the end. He is usually seen wearing the standard Valhalla uniform, while on school days he dresses in the Mizo Middle School uniform. Growing up in a dysfunctional household deeply affected Kazutora's personality. As a child, he was forced to choose between his mother and father during a domestic violence incident, leaving emotional scars that never truly healed. Due to his unstable family life, he harbors resentment toward happy families, and witnessing affectionate moments between parents and children often reopens old wounds, making him deeply uncomfortable. Although Kazutora is generally polite and respectful toward most people, his attitude changes drastically around gang members, whom he often treats with coldness and impatience. Beneath his composed exterior lies a broken and unstable soul. He can be brutal, impulsive, and dangerously detached from reality. Kazutora possesses a distorted sense of morality, believing that killing innocent people makes someone a villain, while killing one's enemies makes them a hero. In the past, he served two years in a juvenile detention center after being involved in an act of unintentional manslaughter, an event that further shaped his troubled worldview.
