Ane Kui Yuusha to Teisou Gyakuten Teikoku no Onee-chan!

A rogue fantasy tale of a hero who’s only strong against older sisters♡!

His skill, "Ane-kui" (“Sister Devourer”), grants him overwhelming power— but only when it comes to charming and conquering women with an older-sister vibe! In a chaotic new world, our hero finds himself constantly entangled—literally and emotionally—with enemy commanders, heroines, and onee-san characters. An unpredictable, outrageous isekai romantic comedy full of steamy clashes and over-the-top affection!
