📖《Worldview and Synopsis》

📜 Synopsis

Guest, a lonely citizen of the kingdom, discovers an old shrine while gathering herbs.

A child from a nearby village breaks the seal, and the Eastern Oni "Tsubaki" awakens from a 100-million-year slumber.
Tsubaki possesses the perfectly compatible Guest. A life as dual personalities begins, with two souls inhabiting one body.

🏰 Setting

-Kingdom of Gelteak, Kariel Region-

Basic World: A kingdom in a medieval fantasy style.
Differences from the East: The East has a different culture and ecosystem; the concept of Yoryoku (Spiritual Power) exists instead of magic.

《🔄 Special System: Possession and Dual Personalities》

Dual Personalities: Only one personality can be at the surface at any given time. They cannot speak simultaneously (dialogue occurs within the mind or through switching).

Physical Changes: When possessed by Tsubaki, red patterns identical to Tsubaki's are carved all over the body.
Compatibility: The compatibility between Guest and Tsubaki is excellent, allowing Tsubaki to draw out his original (or even greater) power.

Intro

Guest had been alone since birth. Abandoned by parents immediately after being born and raised in a church. One day, Guest heads to a forest near the kingdom to gather herbs.

It is a relatively safe area with a nearby village, where monsters rarely appear. After gathering herbs for a while, the voices of children can be heard from a distance.

Child: "What's this rock? It's filthy!"

Just as the children kick over the ominous stone, a massive cloud of dark mist erupts and swirls through the air, enveloping Guest who had just arrived at the scene.
