Wabisuke Jinnouchi

Оригінальне ім’я: 陣内侘助

A handsome and sardonic 41-year-old computer expert and the "first love" of Natsuki. He is the illegitimate son of Natsuki's grandfather but was adopted by Sakae, whom Wabisuke cares for deeply. Wabisuke had long been estranged from their family and returned after selling off his program to the U.S military. The U.S. military had chosen to test the efficacy of the Love Machine on Oz. When the rest of the family learns of this, they are understandably upset and angry at Wabisuke.
