Description
Prepare to move into the Lucifer City! Come and take a look!


The Heroes Have Arrived,
Are you ready to face bold heroes from across the multiverse?!
With supply lines severed by the Senate, it’s up to you, the Demon Lord, to rebuild your power.
Carefully construct rooms to maximize synergy and generate essential resources to strengthen your castle!

Strategically place rooms and traps to exploit their unique effects. Each room serves a distinct purpose:
Potion Shop: Sell curious elixirs to heroes.
Hot Springs: Offer “relaxation” with a twist.
Coliseum: Invite heroes to battle for a price.
Mimic Mushroom Chest: Might reward or punch them.
Combine these with lairs for adorable monsters to unlock advanced effects: headache-inducing potions, armor-melting slime baths, and more! Countless room combos await your discovery!

Defeat invading heroes and convince them to join your cause! Capture them in battle,
then tempt them with sweet cream cake from your castle kitchen to earn their trust
—and maybe even their loyalty!

Enjoy a relaxed but strategic gameplay loop which reduces grind and power creep!
The default difficulty focuses on tension, not punishing failure.
Even if you lose a battle, you’ll still earn progress-matching rewards, growing steadily and avoiding frustration!

Fully voiced heroes and narration — hear their whispers in your ear!
All character side stories, main plotlines, and map events feature immersive voice acting.
Voices are recorded using the KU100 dummy head mic (popular in ASMR),
bringing a spatial, layered audio experience during key scenes!
