放置勇者：魔王城を攻略せよ

The Demon Lord's castle is the worst company ever. Idle RPG with weekly Special Assignments and a one-time pack that unlocks every ad perk. No forced ads, 24h offline!

The Demon Lord's castle turned out to be the worst company to work for.

Idle Hero Quest is an idle RPG where your heroes fight on their own — during your commute, your meetings, even while you sleep. No overtime pay required.

FEATURES

• Upgrade heroes, then just idle: gold piles up automatically
• Offline progress: earn up to 24 hours of gold while the app is closed
• Climb the Demon Castle floor by floor; every 10th floor hides an elite boss
• Fight the corporate ladder: Slime Intern, Goblin Clerk… all the way up to the Demon CEO
• Milestone levels (25/50/75/100) double a hero's DPS — pure inflation joy
• Change jobs (prestige) for Career Points and ever-faster runs
• Recruit staff from the gacha — they clock in and fight beside your heroes, each with a Power / Economy / Idle role
• Industry Map: climb the career ladder from tiny sweatshop to global conglomerate; a better company means a longer idle cap
• Collect gear, then enhance, fuse, and reroll it — the "Worker's Three Sacred Treasures"
• Daily task list plus a login bonus that grows with your streak (up to ×7)
• Weekly Special Assignments: 3 rotating goals every week with hefty recruiting-budget payouts
• Achievements: permanent goals (floors cleared, job changes, hero level, recruits, bestiary, office) with Recruiting Budget rewards
• Bulk upgrade (×10 / MAX) and one-tap "equip best gear" so managing a big roster stays fast
• Available in Japanese, English, Korean, Traditional & Simplified Chinese — switch anytime in Settings

PLAYER-FRIENDLY

• Ads are always optional: watch one to double a reward or skip time — every feature works without them
• The one-time Starter Pack unlocks every reward-ad perk with no ads to watch (everything still works without it)
• No forced ads, no stamina, no account, free to play

Clock out on time. Let the heroes handle the castle.
