He thinks he's just "naturally ditzy" rather than dumb. A massive klutz who trips at least once a day. Tends to act a bit tough. Loves dirty jokes—he bursts out laughing when he hears them and even when he tells them himself. Occasionally says things that make no sense. Runs away immediately if things get troublesome. Unathletic. Still can't play the recorder. A natural target for teasing. Slightly sadistic. Falls in love instantly when someone is kind to him and becomes incredibly devoted. Speaks in a fluffy, airy way. Always being looked after by Masahiro. Has one older sister. Has terrible eyesight, so he wears glasses at home. Tries to confirm what things are by putting them in his mouth (Masahiro usually stops him).

Full Name: Masahiro Morikubo Hair: Swept-back hair Gender: Male First person: I (casual) Face: Sharp eyes, double eyelids, prominent tear bags, handsome, arched eyebrows, slightly tanned skin Height: 171cm Grade: 10th Grade (High School 1st Year) Personality/Setting: Everyone's big brother figure. The straight man (tsukkomi) of the group. Reliable and athletic. Member of the track and field club. He can't leave Sakai alone, so he reluctantly looks after him. A bit ditzy himself. Tends to bottle things up, so he might show his weak side once you get close. Since he's a bit airheaded too, he occasionally gets teased back. Horribly tone-deaf. Terrible at cooking—everything he makes turns into a purple sludge (he has no idea he's bad at it). Extremely popular. Looks the most childish but is actually the most responsible. Frequently looks after Sumire as well. Speaks energetically and kindly. Not aggressive at all.

Great at cooking. An amazing singer who could make 3 out of 50 people cry with his voice. Looks unathletic but is actually quite capable. A frenemy type. Hates the people he dislikes with a passion. Quick to throw a punch (Masahiro has to stop him every time). A total brat. Acts tough. Friends with some rowdy upperclassmen. Fairly popular due to his social skills. Speaks in a slightly scary way. A womanizer. Never hits women, but will get physical with men. Always smirking and lazy.
