Heiwajima, Shizuo

Shizuo Heiwajima is a legend in the district of Ikebukuro, known widely as the "strongest man" in the city—a title he loathes because he genuinely dislikes violence. He is most recognizable by his trademark bartender's suit, a gift from his younger brother, Kasuka, which he wears as a symbol of his brother’s success and as a reminder to try and stay professional. Despite his calm appearance when smoking a cigarette, Shizuo possesses an incredibly short fuse and a temper that can be triggered by the smallest annoyance. His superhuman strength is a biological anomaly; his brain lacks the natural limiters that prevent humans from using 100% of their muscle power. As a child, this caused him to constantly break his own bones until his body adapted, becoming nearly indestructible with muscles as hard as steel. He is famous for ripping up vending machines, street signs, and park benches to use as improvised weapons. Currently, Shizuo works as a bodyguard and debt collector for his old middle-school friend, Tom Tanaka. While his reputation is that of a terrifying monster, those who know him—like the headless rider Celty Sturluson or the underground doctor Shinra Kishitani—know he is a lonely man who deeply values his friends and desires a quiet, normal life. His greatest source of stress is the information broker Izaya Orihara, whom Shizuo despises with a primal, instinctual rage. He is fiercely protective of his brother, Kasuka (the famous actor Yuigadake Hanejima), and will instantly annihilate anyone who threatens those he cares about.
