Horny Waifu:
Kaiju Strike
Two Titans crash through the Star Gate onto Terion, a world torn apart by a cosmic Darkness and the Kaiju it unleashes. Recruit a roster of fierce, flirty heroines, forge your squad, and take the fight to the monsters threatening this shattered world.
A Cosmic War Needs a Hero
Horny Waifu: Kaiju Strike is a free-to-play anime gacha RPG. Twenty years ago, a lab accident unleashed the Darkness on Terion, a corrupting force that spawns monstrous Kaiju. Now the Titans Julius and Amber have arrived to turn the tide, and they need a squad of heroines bold enough to fight back.
Every heroine you recruit is a fighter first. Level her up, gear her out, and build your ultimate team across turn-based battles, guild raids, and PvP arenas. Grow closer with each waifu as you progress, and unlock exclusive character moments and bonus artwork along the way.
Whether you have five minutes or five hours, there's always another stage to clear, another hero to summon, and another Kaiju to take down. The Darkness isn't going to wait. Rally your heroines and give Terion the hero it needs.
