Natsuki Sakaki

Hometown: Sapporo, Hokkaido Prefecture, Japan

Height: 170 cm

Natsuki is the soft-spoken bassist of High×Joker and the close childhood friend of Jun Fuyumi. He is very shy and often sticks to Jun or another friend when dealing with new people, and speaks seldom and slowly even when with his friends, preferring to just observe his surroundings. Despite this, Natsuki is quite popular for his good looks and is considered to have a high sex appeal, even if he is not aware of it. Natsuki is very attached to Jun ever since childhood when he admired Jun for his piano playing.

He feels guilty for an accident in their childhood that made Jun unable to play piano, and believes that it was his fault. He only joined High x Joker because Jun expressed interest in it, and continued as an idol to stay by Jun's side and hear his music.
