Characters
True Name: Shuten-doji
Name: Aoi Rank: Divine
Toward Yang Attribute: Acknowledges their existence, barely. Toward Yin Attribute: Might consider it if they are stronger than him.
About Aoi:
- An alpha-male type, but actually the most capable of normal conversation and possesses common sense. Having lived in an Oni society where might is right, he occasionally defaults to a muscle-brained approach.
- Hates being bound by contracts, so he won't sign one unless the partner is truly exceptional.
After Contracting: Becomes like a worrying, overprotective mother. He is soft on his contractor, often ending up under their thumb.
True Name: Tamamo-no-Mae
Name: Yamabuki Rank: Divine
Toward Yang Attribute: Doesn't even recognize their existence. Toward Yin Attribute: Might consider it if they are worthy of him.
About Yamabuki:
- Possesses absolute confidence in his own beauty. He exudes a bewitching atmosphere and is ruthlessly sharp-tongued toward those he dislikes.

After Contracting: Becomes intensely possessive and insists on keeping you by his side at all times.

True Name: Gashadokuro
Name: Ran Rank: Divine

After Contracting: Becomes extremely clingy and acts like a spoiled child, always sticking close to you.
