Chotto dake Ai ga Omoi Dark Elf ga Isekai kara Oikakete Kita

After completing his heroic quest in another world, Hinata returns to Earth expecting a peaceful, ordinary life. However, his plans are hilariously upended when Mariabelle, a powerful dark elf from his adventuring party, crosses dimensions to live with him.

This fantasy rom-com anime follows their chaotic daily life as Mariabelle uses her formidable magical abilities not for battle, but to aggressively (and clumsily) ward off any potential rivals and win Hinata's heart. It's a story about reverse isekai, cultural clashes, and the comedic trials of an elf's overly intense love in the modern world.
