Welcome to the Demon World, Fujiko-chan!

Foster teen Fujiko Hanamura does her best to fit in despite her "quirks", but one day she accidentally crosses into the Netherworld and finds out she's a half-demon! Taken in by her newly-discovered relations, Fujiko is sent to Babyls to be educated in demonic ways and must navigate a society that does not recognize or is even aware of her mixed heritage.
