Shuuseki Ijuin

Shuuseki Ijuuin (伊集院 秀石) is the president of IPC (Ijuuin PET Company, named BlazeQuest in MegaMan NT Warrior) and the father of Enzan Ijuuin (Eugene Chaud / Chaud Blaze). He is a very cold person, even with his son.

Personality
He is a very cold and strict man, especially when it comes to his son Chaud, whom he expects nothing less than complete perfection from. He expects Chaud to be continually training, and that doing anything else is a waste of time. It is even insinuated he does not let his son eat with him at dinner.

MegaMan Battle Network 3
Shuseki appears in Mega Man Battle Network 3. His company is the sponsor of the N1 Grand Prix. We initially see Shuseki appear with Chaud, who hopes his father will watch him in the competition, but Shuseki simply berates him for wasting his time.

Later on, however, Shuseki is kidnapped and held hostage by Sunayama, who uses him as a bargaining chip when he's unable to beat Chaud in the tournament. He forces Chaud to trade his PET for his father's freedom, but with Lan's intervention he's able to save his father.

Shuseki finally appears at the end, after Lan and co. have thwarted WWW. Although he still maintains his icy demeanor, he seems to open up a little more to his son, despite Chaud admitting that Lan did most of the work.

MegaMan NT Warrior
Shuuseki appeared in a flashback in episode 49 of MegaMan NT Warrior Axess, where he talks with Chaud. A young Shuuseki also appeared in episode 32 of Rockman EXE Stream.

Trivia

 * Shuseki literally means "excellent stone" in Japanese.
