Have you ever taken full stock of Rin Okumura's defenses? Counted them, understood what they could actually do?

Rin knows them all too well.

1)

His teeth, although not as deadly or sharp as his other siblings', could still be considered fangs. He'll laugh them off if someone draws attention to them, usually feigning dental problems. He's built entire costumes around them for Halloween (when he was tired from Shura's training and not feeling particularly creative.)

Quite honestly, those fangs were made for ripping and tearing (though Rin has the blunted version.)

Except at certain times . . .

Yukio stares at the sky worriedly. He takes off his glasses, rubs them, then the bridge of his nose. Rin can't really help but notice this, God knows he's trying not to, and it's starting to drive him nuts.

"Four-Eyes, I'm begging you, I will study like a maniac for the next THREE MONTHS if you promise to quit doing that every five minutes."

"Doing what?"

Rin grunts in disgust, throwing down his book, and heads for the roof, Kuro at his heels.

"You've been a little testy today, Rin. Anything wrong?"

The exorcist looks surprised at this.

"Hn? What makes you think that?"

"For one, you'd normally answer your brother outright, instead of just storming off. For another, even the infamous Rin Okumura hasn't made it a habit of nearly blowing up half the academy over something so trivial as a fight with Ryuji. How'd that one start, anyways? I couldn't get much out of the grapevine."

The eldest Okumura smiles wryly at this, knowing exactly who Kuro means by the grapevine.

"Ukobach clammed up, eh?"

"Yes! Now what happened?!" Rin chuckles as his familiar practically dances on the roof with anticipation.

"Not much, I guess. Just me being stupid. Bonbon asked me about my teeth, just said something about them looking sharper . . . I kinda snapped. Dunno why, it was ridiculous, like I said. I'm guess glad Shura shut me down before I could do anything, though . . . But man, did she have to do it so hard? It felt like she was trying to pull my tail out of it's socket!"

Kuro's look of utter horror is enough to have the half-demon doubling over in laughter.

"She did wha-at? And she's ALIVE? Rin, have some self-respect . . . Wait, all Ryuji did was comment on how sharp your teeth were getting? Back in the demon world, that's a compliment . . ." The familiar's eyes go wide(er) as the answer hits him:

Rin doesn't want to be lumped together with demons. In any way.

The knight-in-training slumps forward on the roof, otherwise sobered. His familiar mutters a sincere apology, but the damage is done. He's about to head back downstairs (to give his master some space) when Rin clears his throat.

"You think I might be turning into more of a demon each time I go all-out?" The demon-cat gapes. This is the single most intelligent sentence he's ever heard come from Rin's mouth.

And he's heard a lot come out from there.

"It's not impossible but-" Kuro is cut short by the youngest Okumura, who seems to have materialized from nowhere.

"Nii-San, I need you to stay inside for the rest of the day, and night. It's an eclipse today and your powers might temporarily get out of hand. Please, PLEASE don't make me watch your every ste-" Now it's Yukio's turn to be interrupted, as he's unceremoniously tackled by his older brother.

"YUKIO! Thankyouthankyouthankyou! Have I told you you're the best best brother that ever lived?! HaHA!" Rin half bounds, half skips down the stairs, leaving a dazed, and more than slightly confused, sibling in his wake.

"Now what was that all about?
