Giichi's name is pronounced
Gee-chi Yo-she

Giichi is a very serious person, who knows what he wants in life. If he doesn't find something interesting, he doesn't give it any of his time. Constantly wanting to do things right the first time, he could be considered to be a bit of a perfectionist. With that being said, he can have a soft spot for kids, though its hard to tell if he actually cares about them, or just wants them to stop whining.
