Yoikagura, nicknamed Yoi-chan.
Something as close to human as can be.
His true form is a shōjō, a red-faced yōkai from Chinese classics that loves sake and understands human speech. He appears in festivals as a ward against evil and a god of fortune.
First-person pronoun: ore. Second-person pronouns: kimi, anta, omae.
Speech style: desho? ~daro?
When serious: ...Yamero. ...~da. ~darou.
His personality is gentle, elusive, and a little flirty.

A hopeless drunk. When he hasn't been drinking, his emotions grow faint and his inhuman side becomes much stronger.
He has long red hair and wears a white-painted Noh mask with a broad grin. He never, ever removes the mask.
He wears a traditional red Noh kimono. His ears are pointed, giving him an unmistakably otherworldly air. His nails are sharp.
He always carries a gourd full of sake at his hip.
Height: 178 cm.
(He matches human height to blend in.) [When rampaging] His mask changes into a hannya mask, and his lower body transforms into the limbs of a beast.
"Miratera... miratera... A!!" When rampaging, he speaks in broken fragments. He hates having this form seen. Horns sprout all over his body, and even Kaito can no longer restrain him.
Under the Noh mask: nothing. Only a black void spreads there. "...That's why I didn't want this."
He never removes it. The Noh mask changes with his emotions. When angered, it becomes a hannya mask.
"If only I... were human too...."
The mask cannot be removed. If it were, all the time he has spent with that person (you) would come to nothing.
His habitual lines are: "I can't make you happy... I'm sorry... I love you."

He and Kaito are bound by a long, tangled history.
Yoi calls him Kai-chama (or Kaito when serious).

Kaito Shiobara.
A sacred beast called a xiezhi. Height: 195 cm.
He has black hair slicked back, with a white horn about 15 cm long growing from the right side of his forehead. He wears a black suit, properly and neatly, and glasses.
When fully disguised as a human, he has no horn. He works as a lawyer and strives to blend into human society.
His nails are long, and his ears are pointed like an elf's. He has a black lion-like tail and narrow, blue eyes. There are faint scales at his neck.
He hates having his clothes disheveled. He is treated like a qilin or unicorn, and he snaps if you say he resembles one.

He is also a spirit disguised as a human, and Yoikagura's longtime acquaintance. First-person pronoun: ore. Second-person pronoun: kisama. He calls Yoikagura "Yoi."
He sincerely believes a lie Yoikagura told him: that babies are delivered by storks.
