Mitsuba Sousuke (Japanese: 三葉惣助) is a ghost haunting Kamome Academy Middle School's lockers.

Appearance
AAAA

Personality
Mitsuba is cocky, foul-mouthed, and very confident in himself, particularly his looks, and often brags about how cute he is. He has a tendency to call people by rude nicknames, and isn't afraid to throw insults. He knows how to get on people's good sides, and sometimes acts nice to someone if he needs to get on their good side. He has also been shown to be quick to cry, especially in threatening situations.

Due to his personality making him a target of bullying in elementary school, he created another, gentler personality in middle school to get along with others better. During this time, Mitsuba is nice, considerate, and friendly with everyone.

He is very fond of his camera and photography, almost to the point of obsession, according to Kou. He was a member of the school's photography club and had won several awards.

Story
Mitsuba was first introduced through a rumor of a ghost that haunts the middle school lockers, grabbing people as they change their shoes and asking them "Do you remember me?". Kou caught him on the act when he grabbed his arm, and after consulting with Hanako, Kou decided to help him finish his unfinished business so he could move on from the world of the living.

Deciding that Mitsuba's unfinished business was that he had a picture he wanted to take, Kou took Mitsuba's camera and they go around the school taking photos of anything that catches Mitsuba's attention. During this, Kou's friend mentioned that Mitsuba had died from an accident during that year's winter, and that he was in the same class as them during their first year.

Mitsuba revealed that he had been bullied in elementary school for his personality, and he tried to be nicer to people starting in middle school, including towards Kou and his friends. The source of the school locker ghost rumors was him visiting people he knew when he was alive, to see if they remembered him. Though, out of everyone he asked, not a single person did. Kou apologized for not recognizing Mitsuba, because he had acted so differently than he did when he was alive, and tells him that they could still be friends even if Mitsuba had died.

As they were making their way home for the day, promising they'd meet again the next day to process the photos taken that day, Tsukasa appeared. He attacked Mitsuba and revealed that Mitsuba had asked him to grant his wish, to stay in everyone's memories, and that he wasn't happy Mitsuba's trying to move on without consulting him.

With the help of Sakura's radio channel, Tsukasa changed Mitsuba's rumor into "The Bent-Neck Boy at the School Entrance", and changing Mitsuba's form and nature along with it. Apparently, Mitsuba's original wish was too vague, and Kou had helped bring out his actual wish, which is to have friends, and to stay with them forever. This allowed Tsukasa to turn Mitsuba into a more powerful supernatural.

The newly-formed Mitsuba who had lost his mind as an exchange for having his wish granted attacked Kou and tried to break his neck. He was successfully defeated by Hanako and disappeared, only leaving behind his camera.
