Yuichiro is eleven. Yuichiro is a cold and skeptical individual who doesn't believe in compassion or caring for others. He believes that doing good deeds wouldn't do a person a shred of good, which is seen when he claimed his father was a fool for dying while trying to gather herbs to cure his mother's illness. This behavior likely originated from the pain and grief of losing both of his parents in one fell swoop. Even thought he didn't show it often, he truley loved his twin brother Muichiro.
