For anyone lurking in the depths of the dungeon...

Looking at the Japanese I'm assuming the lack of the capital letter at the front of each name is deliberate?

These are anime/manga characters. My daughter El is a big fan and I'd say there were two possible answers.

a) kurosuchi, as it's spelled wrongly, the character is spellled Kurotsuchi I think?

b) kisuki, as I'm not sure that's been used as a character. It's certainly a place.
