Mr. Cho is an elderly man living in the same apartment building as Masane Amaha and her daughter Rihoko. He is a highly skilled computer hacker, a talent he uses to assist Masane and Rihoko on occasion. His background before moving into the building is not elaborated upon, but his proficiency with technology makes him a useful ally. In terms of personality, Mr. Cho is introduced as something of a pervert, frequently trying to peek into the women’s baths and making lecherous comments. However, this behavior is a surface-level flaw that masks a genuinely kind and protective nature. He develops a strong sense of responsibility for Rihoko, keeping an eye on her while Masane is away and looking out for her well-being. His motivations are largely personal and grounded in his fondness for Rihoko; he wants to protect her from the dangers that surround her mother’s involvement with the Witchblade. His role in the story is that of a supporting character and occasional comic relief, providing a safe harbor for Rihoko and offering technical support when needed. His key relationship is with Rihoko, whom he treats like a surrogate granddaughter. He also interacts with Masane, though his dynamic with her is more that of a neighbor and occasional helper. There is no significant development of Mr. Cho’s character over the course of the series; he remains a static figure defined by his combination of elderly perversion and heartfelt loyalty. His notable ability is his mastery of hacking and computers, which he uses to gather information and perform favors for the main characters. He has no special powers or combat skills, relying entirely on his technical expertise.
