User blog comment:EmirK/About Kihara Amata's son and espers in Kihara family in general/@comment-5230978-20130712164814

It would great if e was both a Kihara and the Number 6, but if he is, he must have changed his surname or even the name, because otherwise Tsuchi and Touma should know his identity as Kihara.

Ah, one thing: Amata isn't Gensei son.
