The Hundred Youkai Master

The Hundred Youkai Master

A tactical command RPG featuring over 100 yokai.
Form your ultimate Hyakki Yagyō, master deep strategy, and conquer deadly encounters!
Challenge yourself in a battle-focused, high-difficulty RPG—no exploration, just pure tactics.

Designed for players seeking high-difficulty and challenging battles.

A powerless onmyoji leads a hundred yokai into battle—

"Hyakuyoushi" is a command-based strategy RPG with a deep tactical core.

Follow Sei, a young onmyoji who has lost her spiritual power, and the twin nine-tailed foxes Kuro and Shiro, as they embark on a journey to reclaim her lost arts.

A girl without onmyō arts—Haru.

Without pacts nor mystical talent,

she faced the youkai simply as a friend.

Behind her carefree smile lies a will stronger than any spell.

Now, with a hundred allies at her side,

the false onmyōji tears through the darkness.

Dōman, the archenemy who cursed Haru’s master to death.

A genius of orthodox onmyō arts,

he tramples youkai with elegance and cruelty.

To him, battle is beauty—and mockery, his art.

For Haru, this "embodiment of curses" stands as the ultimate wall she must break.
