Shizuo

 Shizuo is an imposing young man, often seen wearing his trademark bartender's uniform and blue glasses. As a child he had brown hair, though he later dyes his hair blond according to Tom Tanaka in middle school. He is regarded by a variety of characters to be a good-looking man who is akin to actor Yuuhei Hanejima, who is actually his younger brother Kasuka Heiwajima.Shizuo is shown to the audience in the very first few episodes as a brutal tough, no-nonsense character, in a similar way to dangerous characters, such as Izaya Orihara as well as Simon Brezhnev. The show implies that he is quiet and discreet and follows Tom around as his bodyguard. Shizuo is said to not enjoy violence and has doubts about his own strength; unfortunately, he has the most irritable temper and, when he is angry, his body "acts independently" and is able to fight with incredible force. Masaomi kida advises Mikado Ryuugamine not to approach the man. He also advises Izaya to avoid him and to keep the Dollars away.
