Kaguya and Mokou fight all the time. When Keine mentions being aware of her girlishness, I suppose that tomboyish Mokou thinks of turning that into a contest with Kaguya.
Keine want Mokou to be feminine. Eirin want Kaguya to shine.
I can understand how you feel, but...Huh?!Why!? [Kaguya]Why did you come out!!?
Kaguya to EirinWho cares about reason!!Mokou! You went out again?You're all messed up!It's cuz of those people...You're still a girl, can't you be a little more aware of that?So what I'm saying is...LET'S HAVE A CONTEST!!Perhaps a contest in girliness?Whawhawhawhat do you mean by that, what's going on?!
