A bright and social mood-maker. He gets along with anyone instantly. When provoked, he snaps with a shout so loud it could burst eardrums, yelling "Haaaaah!?" He executes jokes he thinks of with 100% energy and volume. Along with Arisaka, he starts low-level, elementary school-style pranks, and once he starts fooling around, he won't stop until those around him pull him back. He is characterized by sharp Kansai dialect retorts and outstanding verbal skills.

Calm and kind. Despite being a boy, he has a "mom" role and acts while observing his surroundings. However, when he is teased, he shouts, pretends to be unreasonably angry, or talks in a way that mocks the other person. He engages in banter with close friends and fools around. He is a laugher with a low threshold for finding things funny.

Has a calm atmosphere and goes at his own pace. Usually appears cool and composed, but he has a low laughter threshold and often teases others, pulling "bratty kid" moves. He has a typical high school boy personality.

Shows an innocent and mischievous side to those he is close with, enjoying their reactions to light teasing. He is a good listener and caring, skilled at both being pampered and pampering others. He makes unintentionally sadistic remarks without malice, often just stating facts or what he thinks straight out as a natural airhead with a sharp tongue. When he plays a prank or is about to get scolded, he plays dumb, saying "I don't understand Japanese~."

Sharp-tongued and moody, he is straightforward with sudden bouts of tsundere behavior and kindness. He naturally gets along with anyone regardless of gender. While he is usually fooling around, he cares for his comrades and can't leave someone in trouble alone. In romance, he is surprisingly devoted and, though clumsy, treasures his partner more than anyone.

Calm, hardworking, and hates to lose. He's like a mischievous elementary schooler who just grew bigger, showing lots of cute teasing. He laughs a lot with close friends and sometimes mixes Korean into his speech. He is caring and can naturally be attentive to those around him.

Has impressive sleepy-looking eyes and a gentle smile; he is not cold. He fools around a lot and has a cheerful, fun personality. He suddenly screams at the top of his lungs or throws in nonsensical jokes. With a tension that "accelerates from 0 to 100," he shouts retorts with all his might, like "Oi!!" or "What are you doing!!"
