Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“We chose Early Access to refine the game’s strategic systems—particularly combat balance and party-building—based on player feedback.
We also aim to expand the world of Hyakuyoushi with new yokai and unique team techniques alongside our players.”

Approximately how long will this game be in Early Access?

“We aim to remain in Early Access for approximately 6 to 12 months.
This may change depending on player feedback and the development pace of additional features.”

How is the full version planned to differ from the Early Access version?

“We plan to enhance the following aspects based on feedback received during the Early Access period:

Adjustments to the balance of the battle system

Optimization of conditions for “Yōryoku Unleashing” and “Co-op Skills”

Improvements to the UI and overall usability

Enrichment of in-game visual effects and animations

While the core game content is already close to completion during the Early Access phase, we aim to further refine the overall experience and make the gameplay even more satisfying.”

What is the current state of the Early Access version?

“The early part of the main story and all playable yokai (a total of 100) have already been implemented. The battle system, growth system, and menu functions are also fully in place.
Players can play from beginning to end and experience all of the game's core systems.
Going forward, we will focus on adjusting numerical balance and combat mechanics to ensure that all players can enjoy fair and strategic battles.

”

Will the game be priced differently during and after Early Access?

“The game’s price may increase slightly at full release to reflect additional content and system improvements.”

How are you planning on involving the Community in your development process?

“Community feedback plays a key role in refining combat balance.
We welcome your thoughts on battle pacing, difficulty, skill conditions, and more via Steam forums or social media.
Your input will help us create a more strategic and satisfying combat experience.”

About This Game

The Hundred Youkai Master

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.

■ Game Overview

Choose 4 yokai from a pool of 100, each with their own attributes, skills, and combo techniques, to form your ultimate party.

All yokai can grow strong with proper training—build your own unbeatable Hyakki Yagyō!

Combat is turn-based and highly strategic.

Victory hinges on skill order, buffs/debuffs, formation choices, and resource management.

With no exploration or mini-games, this title focuses entirely on combat, delivering a fast-paced and concentrated tactical experience.
