About the Game

Every night, the yokai march. Every night, you must hold the line.

You are an onmyoji — an exorcist shunned for your forbidden arts of necromancy and yokai subjugation. Banished to a remote fortress, you were forgotten by the world. But when the Hyakki Yagyo sweeps across the land and destroys the capital, your cursed powers become humanity's last hope.

Recruit mercenaries. Set traps. Build your fortress. Survive.

DUNGEON DEFENSE MEETS ROGUELIKE

Inspired by Dungeon Maker, place rooms, traps, and units on a grid-based fortress. Enemies invade each night — your defenses fight automatically. Watch from above on the tactical map, or zoom in to witness every slash and spell up close.

FATE CARDS

Each day, choose one of three Fate Cards to determine your action: battle, shop, fortify, treasure, date, or event. Plan ahead using the branching card map to chart your path through 20-day cycles.

8 MERCENARIES, 22 YOKAI — ALL YOURS TO COMMAND

Recruit beautiful mercenaries and subjugate defeated yokai to fight alongside you. Each unit has unique skills, equipment slots, and tactical AI you can customize.

ROMANCE & ULTIMATE SKILLS

Date your allies to deepen bonds. Complete three dates to unlock rank upgrades and devastating ultimate skills with cinematic cut-in animations.

THE NECROMANCER'S PRICE

When a mercenary's life points reach zero, they become a Battle Puppet — a silent, soulless weapon of terrifying power. You gain a Legend-rank fighter with their ultimate skill unlocked. But they will never speak again. Was it worth it?

BOSS BATTLES & WORLD ESCALATION

Face powerful bosses every 20 days. After each victory, the world grows stronger — you choose how. Enemy HP, attack, speed, or even AI intelligence escalates with every cycle.

HOW LONG CAN YOU SURVIVE?

There is no safe ending. The nights only get harder. Push your fortress, your mercenaries, and your conscience to the limit.
