The more you care for your adorable companion, the stronger your bond becomes.

――This is a small and sorrowful tale about a boy and his dog.

3D action anyone can enjoy, with depth for those who want to master it

Enjoy fast, responsive battles where you are not restricted by stamina.
Attack, dodge, guard, parry, and use jump actions freely.

This is not a game that forces difficult controls on you.

And if you have confidence in your skills, battle becomes even more stylish.
Almost every attack can be parried and deflected.

A casual mode is also available, letting you focus on the story and your journey with Musashi.

The dream of adventuring with a dog

That simple dream lies at the heart of this game.

Play together.
Feed him.
Strengthen him.
Dress him in outfits such as ninja or samurai attire, and he will support you with new powers and team-up attacks.

Musashi is not just cute.
Caring for him makes you stronger.

But Musashi is already a being whose soul has been taken.

Because he is cute, you want to pet him.
Because he helps you, you come to rely on him.
The more time you spend together, the less you want to lose him.

That is why this journey is not only fun.

Every moment spent caring for Musashi becomes a precious memory — and a bond you cannot let go of.

A world where strange and lovable Mononoke remain

In a Japanese-inspired otherworld abandoned by the gods, strange, charming, and somehow lovable Mononoke continue to live.

At first, they are cold toward outsiders.
But as you restore their village and solve their troubles, they gradually begin to accept you.

They laugh, worry, get angry, and help one another.
This world is still alive with lively Mononoke.

Do not merely defeat the yokai — discover who they truly are

Yokai reimagined from Japanese folklore and legends await you.

But they are not simply enemies made to be defeated.

Why did they become yokai?
What are they angry about?
What memories can they not let go of?

When you learn the truth beyond each battle, the terrifying enemy before you begins to look different.

Do not simply strike them down.
Touch their hearts, unravel their regrets, and calm their souls.

Uncovering the true identities of legendary yokai is one of the great purposes of this journey.

The boy carries Musashi’s fate forward

To reclaim Musashi’s soul, the boy draws closer to the vengeful god.

But is restoring a lost life truly salvation?
What must he bear in order to save this small companion?

The shrine maidens and heroines he meets on his journey each carry their own beliefs.

Those who believe in salvation.
Those who accept sacrifice.
Those who resist the curse.
Those who choose to witness fate.

You play as the boy who wishes to save Musashi, experiencing his conflict and the decision that awaits him.

Beyond that decision lies the end of this journey.
