Katsuro Okada, the ultimate Salesman. As one of the more responsible of the group, Katsuro is usually one of the ones making the big decisions. He's even taken Kenji under his wing, often calling him "son" despite being only a year older than him. Katsuro is very thoughtful, but somehow still holds back his peers from further succession due to his refusal to grow with them. He always worries, how far can he really get as a Salesman?
