After seeing a bit of him last week, we’re formally introduced to another new Souma, Haruhatsu, who seems cool to some passing ladies until he gets on his deeply uncool bike with his uncool shades, clearly on some kind of mission.
Winter break is over, and Tooru has settled back into a fun daily life with the Soumas, though Yuki and Kyou remain stubbornly incapable of getting along. As it’s wintertime, Yuki also feels a cold coming on.
Despite this, Yuki doesn’t back down from Kyou’s challenge to beat him in the endurance race on the first day of the third term. Sure enough, the two blast ahead of all the other boys. Meanwhile, Uo skips entirely while Saki dramatically quits after one step and plays cards the rest of the time, to the annoyance of the teacher.
Kyou is literally tripped up by Haruhatsu, who wanted to fight Kyou on New Year’s but wasn’t able because Kyou skipped the family festivities. Now it’s go time…and Kyou isn’t one to back down from a fight.
Their mutual competitive spirit results in the emergence of “Dark Haru”, Haruhatsu’s other, more manic side, like Kagura only worse. Haru reiterates his undying love for Yuki while fighting Kyou like they’re in some kind fo martial arts movie.
Yuki notes that the two trained together when they were younger, and are both equally passionate about it. Tooru suspects Yuki loves martial arts too, but when he recalls a memory of watching the other two sparring and having his eyes suddenly covered by Akito, he faints.
The fight is called, and Haru decides the best way to get Yuki home is to carry him on his back in animal form, which is that of the Ox (though technically a cow).
When it’s just Haru and Tooru, he tells her the story of how he was always angry and losing his temper, and hated Yuki’s guts because of the “rat who rode the ox’s back” legend, and also because everyone always called him stupid and an idiot, for which he also blamed Yuki.
That all changed when he finally met him, and Yuki told him he wasn’t stupid; not really. He fell for him right then and there. With that, Yuki wakes up, not the worse for wear.
Haru suspects Tooru has had a “lightening” effect on the once standoffish Yuki and Kyou, and proves there’s something between Yuki and Tooru when he has the latter call the former by his given name and he immediately transforms into a rat.
Meanwhile, Saki has drawn a crowd to play poker by the school gates, but beats everyone running away (not literally though, as Saki isn’t fond of running). As a result of playing cards outside all afternoon in the cold, Kyou and Shigure also get colds. But Tooru is all too happy to take care of them!
