Ep 10 – “Make It Clear If It’s Black or White” / “Dai Juu Wa” (第十話)
Yuki comes down with a fever. Although Tohru tries to convince him to stay home, he accepts a challenge from Kyo to a contest: he must win the endurance run at school the following day. Tohru meets Hatsuharu, the Ox of the Chinese zodiac, during the endurance run. It is shown that Hatsuharu also has dissociative identity disorder, and he intentionally trips Kyo during the challenge against Yuki. He has come to challenge Kyo, and the two engage in hand-to-hand combat. However, as Tohru and Yuki watch the two fight, Yuki feverishly collapses. Hatsuharu clasps Tohru, to which he transforms into a cow, instead of an Ox, and is to carry Yuki back to the household residence. Later on, Hatsuharu explains to Tohru why he used to hate the clever Rat for insulting the foolish Ox. However, he further explains how he later forgave himself for being envious of Yuki.
