Jonouchi Katsuya's Father
Jonouchi and Shizuka's dad struggled with serious problems—heavy drinking and a gambling addiction that spiraled out of control. After he and his wife split up, he stayed with Katsuya while Shizuka went to live with their mother.
The gambling debts he racked up became Jonouchi's problem to solve. Eventually, Katsuya managed to pay them off, which is a big part of why he gets involved in the high-stakes card games that define his story.
