Mizuno Katsuro

Mizuno Katsuro is a middle-aged man who works as a nomadic oddity specialist who collects information, reinforces balance, and helps resolve cases.

Early in the series, he lives with Natiko in Eikou Cram School. He helped Osuna Tobiichi to return to normal after being bitten by a vampire, and becomes his informant when it comes to oddities for some time.

For most of the series, he's missing after leaving town seemingly unannounced.

Appearance
Katsuro is a man with a lanky physique, short hair that's dirty blond and blue eyes. He keeps his hair in an unruly fashion (although he sweeps it back when he performs Shinto ceremonies) and has a pair of sideburns and a goatee. His outfit consists of a pink aloha shirt left unbuttoned, a pair of dark-colored cargo shorts and black sandals that resemble the Japanese geta. Katsuro's notable accessories include an earring on his right ear and a necklace, both having an inverted cross on them.

Katsuro's overall looks give off an eccentric feel to people he interacts with, and even Osuna calls him a "psychedelic aloha guy" because of this.

Katsuro is often seen with a cigarette in his mouth, although it is never lit.

Personality
Katsuro's personality is quite laid-back and can be somewhat eccentric. Along with his unusual fashion sense, his current residence gives off the feeling that he is not a normal guy like most people.

As someone who is involved with the paranormal, he prefers to keep himself from directly meddling with affairs involving oddities, though he has the strength to do so if need be. He generally prefers to help out, but only if the person themselves is willing to exert effort towards returning to normal. However, putting aside his financial priorities, he can be well-trusted in supernatural affairs, with his knowledge that is useful in handling cases related to oddities.

Background
Katsuro is a graduate of Shinto studies in college, although he never pursued the career of being a Shinto priest. During his time in college, he was part of the Occult Research Club with Eremiya Morishi, Okuda Shigeru, Ramsey Nishio, Anzai Tadatsu, and contributed to the creation of Atlas.
