Kazuomi Ōga

Kazuomi Ōga (大神 和臣 Ōga Kazuomi) is a third-year student at Aoba High School, and a close classmate of Arata Kaizaki after he became a teenager. He is very smart and always gets the highest score among the boys in his grade, which is why he is recurringly selected as the class representative. This, along with his appearance, contrasts with his poor athletic ability and denseness when it comes to romance.

Appearance
Kazuomi has light brown hair and brown eyes. While attending Aoba High School, he wears his elder brother's uniform (white shirt, black tie, dark gray full trousers and a light gray full sleeve sweater), which happens to be too loose on him.

Arata has also called Kazuomi good looking multiple times.

Personality

He's seen as being dense in the matters concerning love and relations as he did not know about Kariu's feelings for him.He cares for his friends very much, and often looks up to Kaizaki for advice. He also feels embarrassed after mentioning that he has a girlfriend as a way of boasting to Kaizaki.

History
He has said that his family doesn't have a large amount of money, which is partially why he works so hard to be top of his class. This way his family doesn't have to pay for his meals. He seems to love his brother very much, getting one ear pierced by him.

Relationships
