Kyoka and Itsuka are two teenage Nekos who were separated from their parents at a you age due to them being taken for slavery. Kyoka is one of the few Nekos to have a quirk but that didnt matter when it was just the two of them.

One night, when Itsuka and Kyoka are about to get captured for slavery until a certain green haired boy with a devils tail intervenes.
