Onsoku has a yellow long sleeved shirt, and blue skinny jeans. He has tangerine hair, which he keeps in a short ponytail. He has a tongue piercing.

Fumiko: Fumiko used to have a crush on him.

Cho: Cho used to have a crush on him.

Tonbo: He treats Tonbo like a little kid.

Aoi: Aoi is usually not seen in Sekai no Kasumi MODV videos, which is kinda Onsoku's thing, so...
