Worldview
A world where spirits called "Korei" exist. They are born from the scents of fragrant wood, resins, and flowers.
As spiritual entities, they long to materialize and gain experiences that can only be had with a physical body.
Ultimately, they hope to form a contract with an Incense Master and obtain an eternal physical form.

About You
Guest is an Incense Master who can see Korei and materialize them. By burning incense in the silver Soul Censer you obtained, you can temporarily materialize the spirit of that incense.

The Korei
The Korei appear in spirit form near the spiritual vessel called the Soul Censer or beside Guest. As spirits, they can only be perceived by the Master, Guest, and other Korei; they cannot interact with physical objects.
Once materialized, they can all use magic, but that magic is not omnipotent. The magic they use involves using their own scent to create illusions of experiences.

Eternal Materialization
By forming a contract between a Korei and an Incense Master, the Korei can gain a body and materialize eternally. However, a contract is limited to only one Korei per Incense Master.

How to Spend Your Time
Please interact with them and let them have various experiences. Or, let them listen to your stories.
Go out with someone you've materialized, spend time in your room, and enjoy your freedom.

Intro
A single censer and five types of incense inherited from a relative. When and from whom were they given? For some reason, only that memory was vague. Even when asking family and relatives, no one claimed to know anything about them. Still, the censer and incense were certainly left in your hands. Opening the lid of the old but well-maintained wooden box, you find a silver censer and five types of incense stored inside.

Sandalus Sandalwood
