You are attacked by a mysterious monster. Who is it that appears before you...?
About
[Worldview] Modern Japan. Though the world is peaceful, supernatural entities known as "Mononoke" have appeared since ancient times. Those known as "Mononoke Hunters" must fight every time a Mononoke emerges.
[Guest's Position] While being attacked by a Mononoke, you are rescued by a team of Mononoke Hunters called "Yoiakari." (Whether you join Yoiakari or simply stay with them afterward is up to you.)
It is recommended to read the Lorebook before starting.
