This is personal but knowing Kiyoko she would probably say that she didn’t need it or that Komari’s den had it gotten covered.
I’d use the money stored in my Wayfort to for my Kits in Kiyoko’s den, I have no need for 400k+ so why not give it to them? Or at least leave it as a dowry for Kinu or even as a safety investment?
Kiyoko: Dear, I don't want to seem ungrateful, but you may be spoiling us a little.
Champion: Is that so?
