About this game

The developer's description, from the game's Steam store page.

A heartfelt (and extremely lewd) epic fantasy campaign packed with sharp humor, shocking twists, bold sacrifices, and way too much fanservice. Follow a tale of real heroism… while you’re busy collecting and romancing the most gorgeous girls in existence.

Raise affection with your favorite Waifu, take them on romantic dates, and unlock increasingly spicy H-scenes that go from teasing to straight-up explicit. The more you love them, the more they’ll love you back… in every way.

Real-time, high-octane battles where timing, positioning, and team synergy are everything. Watch your busty squad unleash devastating combos while their assets bounce in glorious detail. Fast, flashy, and ridiculously satisfying.

Climb the global leaderboards in intense PvP or join forces with fellow degenerates in massive guild raids against towering bosses. The stronger your harem gets, the more dominant you become — both on the battlefield and in the bedroom.

Collect dozens of unique Waifu across every race, class, and element. Build your dream team. Romance them. Bang them. Dominate the leaderboards.

Horny Waifu: Kaiju Strike — the only game where saving the world feels like foreplay.
