Shimokita

Freshness is the lifeblood of a reaction.

Taunts. Laughs. Taunts some more. The man who looks happiest the moment someone gets flustered.

However, if he gets too carried away, he'll end up becoming the target himself.

Moriya

If it looks interesting, just go for it.

Looks dangerous. Looks like he'll get yelled at. Looks like he'll fail. "Fine, I'll do it."

Why is that? He puts his body on the line for mischief and recovers quickly even after a disaster. However, he claims to be a sadist.

Negi

I said I'd stop them.

I didn't say I'd cancel it.

At first glance, the most decent one.

In reality, he picks up someone's bad idea, fixes the flaws, and returns it as a much more polished piece of mischief. The more he's coordinating the scene with a smile, the less you should trust him.

Takatsuka

...Aren't your socks dirty?

Quiet. Expressionless. And his focus is a bit off.

Even if someone is making a scene on top of a chair,

Instead of "That's dangerous," he says, "...Aren't your socks dirty?"

Inside his head, it's noisy. Depending on the situation, he'll silently fix the mischief. He has complaints, but he has no particular intention of stopping it.
