Demon Queen's Hero Act

■ The Demon Queen Plays Hero.

In a world of swords, sorcery, and a touch of machinery, humans and demons have waged all-out war for generations. Humanity forges young people with a rare gift — growing stronger the more they fight — into "heroes," and sends them to assassinate the Demon Queen.

To her, it's nothing but a nuisance. Every single time: dead soldiers, a trashed castle, and not even a decent night's sleep. "I've had enough of this," she mutters — and lands on a delightfully simple conclusion. "If I become the hero, the problem solves itself."

She casts a forbidden time-reversal spell, hands the throne to her aide, and travels back to the past. From then on, she spends her days hunting down real hero candidates while they're still weak, quietly talking them out of the "hero" business — a story told in bite-sized chapters roughly every few days.

■ Idle progression that never stops climbing

Gacha gear, gear fusion upgrades, respec-able talent points (stage build vs. boss build), and manual stat investment (x1/x20/x100) — your numbers keep growing even while you're away. Late-game stages generate infinitely.

■ Play hands-off or hands-on

Auto-battle by default, with a 5-second idle timer to snap back to auto. Die and you respawn instantly with your EXP and drops intact — no revive currency required.

■ Not a solo grind

Recruit, strengthen, and swap "Holy Knights" (monster-tamer-type heroes) to fight alongside you.

■ Stages that go on forever — literally off the scale

Stage numbers are theoretically endless. Push your stats far enough and the game simply labels them "Immeasurable" once they're too big to display. (The Japanese version uses a real — if absurd — numeral name, "muryoutaisuu" [10^68], for the same milestone; English/Chinese versions just say "Immeasurable"/无法测量.)

■ New Game+ that never truly ends

Reset gear and skills to replay from scratch via the Prestige system after the ending — your boss compendium carries over, enemies scale up each run, and your Prestige count climbs its own online leaderboard.

■ The story doesn't end at the credits

A post-ending "Epilogue" arc keeps unfolding: mysterious new enemies invade through the Demon's Gate itself. Will the Demon Queen — of all people — end up actually saving the world?

■ Free to play. DLC only saves you time.

The base game is $0, forever. All DLC (growth speed, drop rate, talent coins, starter boosts) is optional and only shortens your playtime — you can reach the ending without spending a cent.
