After a little hiatus from the main plot, it comes storming back into focus here when Haru goes “really” Black and smashes his class homeroom.

Yuki: Haru, what on earth are you doing?

Haru: Letting loose. Ain’t that obvious? If you want to stop me, you can try, but better be prepared to die.

Yuki: Haru, I don’t know what set you off, but don’t get violent at school.

Haru: Always the worrywart, Princess Yuki. You mean you don’t want me to lose it and transform because that would take you down with me. […] The hell with it! Tiptoeing around half the time, it’d be a relief to get it all out in the open!

Then he grabs Tohru, but Kyo is having none of it, hitting Haru and removing Tohru from the line of fire.

Haru: Ah, I feel much better.

So Mayuko-sensei takes Haru off to face discipline while the gang tries to piece together what’s bothering Haru so much.

Yuki: What happened to make Black Haru come out for real, Momiji?

Momiji: I wasn’t watching him the whole time…he seemed normal to me, but maybe something’s happened recently? How do I put it? He hasn’t been himself…

Yuki volunteers to talk to Haru and see if he can get some answers, and Kyo warns Tohru to stay away from Black Haru.

Kyo: He’s dangerous when he gets like that.

Tohru: Um, but that would be rude to Hatsuharu-san.

Kyo: Argh! You just don’t get it! […]

Momiji: I don’t want you near that guy! I bet that’s what Kyo wants to say!

Haru: Yuki, you should call her just “Tohru” too.

Yuki: Hold it, this isn’t about me, dammit! The one we should worry about is you, Haru!…Haru, you’re always worrying about everyone else. I’m always so focused on myself. (internally) Even now, I’m keeping the lid on feelings I don’t want to admit yet. I’m a joke.

This might not be about Yuki, but it is all about love.

Haru: I was dumped. I didn’t feel anything at the time, but as the days went by, I got more and more irritated, and when I thought about it today, it pissed me off and I just snapped. We’d kept our relationship secret. This is actually the first time I’ve told anyone, since we are fellow members of the Zodiac. She changed after that serious injury – I’d go visit her in the hospital , but she’d duck out of her room. Suddenly it was like, I didn’t know what she was thinking. Then she dumped me out of the blue, and I got no idea why. No idea, but even so, I wanna see her so bad it hurts. (internally) My feelings of wanting her are not light enough to give up on her so easily.

All the other times we saw Black Haru, he was just irritated. This time he was really hurting.  His delayed reaction is understandable, considering that he’s always thinking about the feelings of others first.  He doesn’t want to bother anyone with his problems, so he shoves them to back of his mind where they just fester and grow until he can’t contain it anymore.

And since this isn’t really spelled out for a while yet, I’ll briefly explain about Haru’s (ex?)girlfriend.  As you may have guessed, it’s the very same Rin who was mentioned back in chapter 38 – you know, the one who faced the wrath of Akito, although it would seem that Haru doesn’t know just how she was injured.

I’m sorry…I apologize to the whole world! I’m sorry for paying a visit!

Tohru: Ricchan-san?

Until next time…
