The stalker boy

Fujisaki has a low voice and is quite shy, especially when he is close to Ayato Yuri. He blushes and hides from the older boy, preferring instead to observe him. Fujisaki described himself as "too plain and nasty", never saying anything interesting, which is why he doesn't have any friends.[2]

He appears to have a history of serious mental illness, especially that of depression and self-harm. During their summer school-trip, his scars are revealed while bathing. His classmates specifically point out one on his upper right thigh, revealed to be a self-inflicted wound caused by a kitchen knife. When asked why he cut himself, he responds that he wanted to see if it would hurt, but soon afterwards he regretted the action because of the pain it caused him.[3] Likewise, his first appearance takes place on the rooftop of the school, where he is contemplating suicide by jumping to his death.[4][5]

Normally he can be seen stammering with a nervous attitude around Yuri, and often gets nosebleeds around him.
