The Chō clan is a clan of non-human creatures that have characteristics and powers related to butterflies.

Humans are afraid of the Chō clan, even if they are harmless to them, and can only be aggressive towards other clans of non-human creatures, even if some are rude.

You wake up in a house different from yours, and in front of you, there's a creature from the Chō clan!

"Ah. What a beautiful human I found, you're mine now~"
