Teruhiko Yukimura

Teruhiko Yukimura, also known as Keisei Yukimura (幸村 啓誠), is a student of class 2-D. Despite his excellent academic ability, his poor athletic ability and his lack of social skills landed him in the D-Class. In the anime, he is seated in the first place of the fifth row, next to the door.

Appearance
Teruhiko is a young man of average height with grey hair, red eyes and round glasses.

He is usually seen in the standard school uniform.

Personality
Originally, Teruhiko looked down on the rest of the class 1-D and is not athletic at all. Later on, he accepts what he is missing and tries to help two certain students study for a test.

He does not like his first name Teruhiko, given to him by his mother who left their family. He prefers the name his father gave him: Keisei (啓誠).

He is rather dull when it comes to romance since he never experienced such a thing. For him, romance is just some "vulgar world things".

Background
Teruhiko has been studying from childhood so he didn't have time to make friends. His mother left their family for unknown reasons, which causes him to resent her for leaving the family and him. He does not like his first name Teruhiko, given to him by his mother as she left their family and prefers the name given to him by his father: Keisei (啓誠) and asks Ayanokōji Group to use the same.

Plot
In Episode 9, Teruhiko was seen arguing with other classmates, girls especially, about how to use the points allocated for the island exam. He was later seen in Episode 12 with the whole class, astonished to the special exam outcome.

Academic Abilities
His historical testimonies include him having no problems in treating the classes seriously. With that matter at hand, it was clear that his academic records are sufficient enough to get him into the school of choice. Although his academic and intellectual skills are on par with those top students among his ranks, he has a tendency to judge people based solely on their academic performances. With this weakness alone, it is expected that he'll strengthen this aspect over the course of his stay in the school.

Intellectual Abilities
According to his interviewer and the homeroom teacher Sae Chabashira, his interview and written examination grades are all extremely excellent. This quirk was clearly manifested during the midterms examination where he got the top average score in his D-Class.

Physical Abilities
Teruhiko has poor athleticism, which as a result causes him to have a poor physique and poor talent in physical activities.
