The Ox of the Sohmas with the "Black" Side
Hatsuharu is the ox of the Sohma family curse and tends to have a two-sided personality. In normal circumstances, he is a calm, friendly, and easygoing young man. But when angered, Haru can become an aggressive, rude, and violent fellow who is especially dangerous to be around since he was taught martial arts by Kazuma. This rude and aggressive side to Haru is refered to as his "Black" side.
As a child, Haru was regularly teased because of being the dumb ox in the story of the zodiac animals where the rat jumped on top of the ox's head unnoticed during the banquet for the animals. This teasing led Haru to blame Yuki for being called stupid by others. However, Yuki points out that Haru isn't responsible for the past actions of the ox. Since then, Haru has come to strongly admire Yuki and can quite frequently be by his side when they meet. Haru is a year younger than Tohru, Yuki, and Kyo as he later attends the same high school that the three go to when they enter their second year.
Haru has also had an on-again, off-again relationship with Isuzu. Haru had come to the defense of her when she was disowned by her parents at the hospital as their relationship builds up to become a sexual one. Following Isuzu's hospitalization from her encounter with Akito, the girl breaks off their relationship leaving Haru unaware of the threats Akito made towards her.
