Kyou kara Tsukaeru Isekai Ren'ai Manual — When Love is a Battlefield

About this series

Haruchika’s confession gets cut off when a goddess yanks him into a world where seven heroines’ hearts are locked tight by a Demon King’s curse. These women are destined to give birth to heroes, but without love, the future—and Haruchika’s only ticket home—vanishes. Juggling chaotic harem antics, magic battles, and surprisingly deep moments, he’s got to crack the curse or lose everything. If you like fantasy romance mixed with sharp comedy and unexpected drama, this one flips the usual isekai script in a fresh, fun way. Seven locked hearts, one guy, and a curse that’s anything but ordinary—think you can handle the chaos?
