Jinnouchi, Wabisuke

陣内侘助

A handsome and sardonic 41-year-old computer expert, and Natsuki's "first love".
He is the illegitimate son of Natsuki's grandfather, though he was adopted by Sakae, whom Wabisuke cares for deeply. Wabisuke had long been estranged from his family and returned after selling 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.
