久保田　杏

Waka’s peer and classmate.
She’s a thoroughly eccentric girl, and her ideas about reality differ significantly from those of the average person.
Her ”occult research” drives her to indiscriminately pursue paranormal phenomenon.
She runs a memberless enthusiast’s club for fans of the subject and releases an unauthorized newsletter once a month that has some value as reading material.
Anzu is also a conscious iconoclast to the point where most people think she has a screw loose in her head.
Because of this, she has very few friends. The one person who accepts her is Waka, whom she trusts unconditionally.
For some reason, she has a brusque manner of speaking.
