I vote Zashikiwarashi as seme But.. Kouta is such a good competitor😣.. Can we just make...

But that would leave out Boku, who I'm hoping is planning to bang Kouta & make him his "dream prepper" :p

But didn't he get interested in the editor in chapter 2.

Aha, you're right :)
That leaves Tanuki-sama, who can appear as a dozen guys if he wants to. That would keep Kou preoccupied, i guess ;)

I also have this tingly feeling about Kouta and Boku.
