Hey now. Kaoru's doubts were mostly due to him still not knowing how Seimei's powers or his shikigami work. He couldn't help it.

He couldn't help but puff up a little indignantly, not so much at the call to be attended (he was close friends with Tamaki, after all) but more at being called a child. As far as he was concerned, he wasn't one though... he relatively speaking, he supposed, it was the case.

Eventually he dipped his head in consent, glancing at Seimei.

"Fine. Call if you need me?"
