Heroines you will meet
Isekai: Waifu Overlord came out on Steam on September 25, 2026 and also runs in the browser and on Nutaku. A truck, a goddess called Divitaya and a run-down village later, these are the girls who help you rebuild it.
What you do in the game
Put the girls to work
Every heroine boosts the building she works in. The right girl in the right place earns more.
Auto-battle the Expedition
Sakuya clears waves and bosses on her own. You choose her gear, her class and who fights at her side.
Summon new heroines
Rare, Epic, Legendary and Mythical girls — a Legendary one is guaranteed within 120 summons.
Win their hearts
Gifts and dates take each girl from Stranger to Partner and unlock her scenes.
Story with a wink
A truck, a vain goddess and a village of heroines — told in voiced scenes with answer choices.
Your village is waiting

Questions and answers
Is Isekai: Waifu Overlord free?
Yes. It is free to play on Steam, Nutaku and in the browser, with optional purchases.
Can I play without downloading anything?
Yes — the browser version runs at isekaiwaifuoverlord.com with nothing to install. Steam (Windows, macOS) and Nutaku's Android APK are the download options.
Why can't I open the Steam page from Germany?

None has been published yet. Codes go into Settings → Promo Code → REDEEM; the promo codes page has the steps and the free rewards.
