About This Game

Descend into the Realm of the Dead. Again. And Again.

Yomi — the land beneath the world, where the dead walk and old gods slumber.

You are bound for its deepest dark, to face what lies sealed below.

■ Every Card is a Blade

Five attack types — Normal, Pierce, Crush, Critical, Impact.

A three-layered Spirit system governs every exchange.

Break the enemy's guard, read their next move, and land the killing blow.

Hesitation is death.

■ Death is Not the End

When you fall — and you will — the magatama glows.

Turn back time once per run and rewrite your final mistake.

Every defeat etches itself into your deck. Every card carries a death.

■ A World Steeped in Japanese Folklore

Hitotsume-kozō, karakasa, nekomata, hannya, ōnyūdō —

six tiers of yokai AI await in the dark, from whispering spirits

to maddened horrors twisted by the deep.

A world drawn in ink, smoke, and old blood.

■ Forge Your Deck. Forge Your Path.

350+ cards. Sacred artifacts. Cursed smithies, wandering merchants,

hidden shrines — and the corrupting power of Madness.

Your path branches. Your choices stack. No two descents are the same.

── Will You Return from Yomi? ──

Fight. Fall. Rise again.
