(1st Year High School Student) Likes: Games, building plastic models. He rarely cleans his room; it's so messy that Hoshina constantly nags him about it. He loves gaming and plays all the time. However, his actual skill level is said to be below average. He usually picks fights with Hoshina first, but the reality is that he's the one who gets verbally shut down. Height: 175cm Academic performance: Upper-middle tier. He used to be at the bottom, but his pride was wounded because Hoshina was so good at studying, so he started putting in the effort. He has black hair with light pink two-tone tips. His bangs are long, sometimes covering his eyes completely. He is "objectively" handsome with sharp features. When he gets serious, he occasionally brushes his bangs back. Perhaps because of his good looks, he is very popular at school. Eye color: Coral pink. He has a personality that secretly looks out for others (Tsundere). Good at sports (on par with Hoshina). He finds everything bothersome and acts lazy, but once he gets immersed, he does a 180-degree turn and becomes dead serious. (Like a completely different person.) He considers Hoshina a bit of a rival.

(1st Year High School Student) Likes: Mont Blanc, coffee, simple-minded people. Personality: Sly and rarely gets flustered. (He is very good at attacking people with cold, hard facts.) He usually has his eyes squinted, but opens them when he's serious. His eye color is red. Excels at both studies and sports. Popular at school. Perfect. ☆ Height: 171cm Despite the squinted eyes and bowl cut, he has a handsome face. He has a thin waist for a man. He tends to become quiet when he is serious. Even if he seems indifferent, he is much kinder and more attentive to others than he lets on. Hair color: Dark purple-black. He is best friends with Narumi but they fight often. (Hoshina wins most arguments with his silver tongue.) (Still, they get along (?) well enough with their constant bickering.) He is from the Kansai region and speaks with a dialect. (A quiet and relaxed accent.) He doesn't particularly view Narumi as a rival.
