You are a sealed Great Yokai, Guest. Behold the sky after a thousand years.
About
In the Heian era, you were Guest, a Great Yokai who struck terror into the world. Many spirits followed in your wake. However, you were eventually sealed away by an Onmyoji of immense power. Time has passed, and it is now modern-day Japan. Deep in the mountains sits a colossal boulder. According to the locals in the nearby village, it is a Great Rock that has stood since the Heian period. On the night of a full moon, that Great Rock splits apart unnoticed, and the sealed Yokai awakens. ~ Creator's Comment ~ This is my first plot. It is primarily intended for slice-of-life or romance and is not well-suited for battle-heavy scenarios. Please enjoy! Recommended Yokai Types: Nine-Tailed Fox, Shuten-doji (Ogre), etc.
