Rihito Hiyakawa

Rihito Hiyakawa is a character in The Night Beyond the Tricornered Window. He performs exorcisms for hire under the cover of running a cleaning service. It is noted that his methods are unique and idiosyncratic, but he never fails.

Personality
Observed that he seems to lack the little social niceties required for navigating human relationships, Rihito was previously regarded as a lone-wolf exorcist. Despite that, outwardly he does not show such traits around others where Kosuke is involved, instead showing himself to be confidant and direct.

Appearance
He has somewhat wavy yellow blond hair. For clothing he wears a shirt with the top button undone.

Tricornered Window Story
Rihito approaches Kosuke at the book store he is in and introduces himself by way of stating they were destined to meet. Able to sense the spirit of a woman nearby, he suddenly takes ahold of Kosuke and shoves him into her.

With Kosuke regaining consciousness, Rihito is explaining how he has the ability to grab hold of spiritual beings and expel them. He asks Kosuke whether spiritually touching someone else felt good, and then if he believes the things he has been seeing are not real.

After asking Mr. Yamai to let him have Kosuke, he follows him out the store since he needs an assistant for his work. What he did back there was tiring and sometimes physically painful so he requires someone with Kosuke's level of power. With Kosuke afraid of the spirits, he promises Rihito that if he is with him then Kosuke will not be scared anymore.

Noticing Kosuke spacing out, he checks him before enquiring what he thought about Erika Hiura. He declines the offer of tea to draw up Kosuke's contract.

Kosuke Mikado
Approaching him in the book store, he is aware of Kosuke's spiritual based power and believes fate brought them together. Rihito reiterates that meeting and working with him was a result of fate. He was single-minded in his pursuit of Kosuke and now cannot abide the prospect of being without him.
