Description
Natsuki Sakaki is one of the idols of 315 Production and a member of the unit High×Joker. Before becoming an idol, he was the bassist in his school’s light music club. He has been close friends since childhood with Jun Fuyumi, and it was under Jun’s influence that Natsuki first joined the club’s band. That same friendship carried over into the formation of High×Joker, a unit that also includes Hayato Akiyama, Haruna Wakazato, and Shiki Iseya.

Natsuki is a particularly quiet and soft-spoken person. He speaks seldom and slowly, even among his close friends, and often appears lost in thought or absentminded. When faced with new people or unfamiliar situations, he tends to stay close to Jun or another trusted friend until he feels at ease. He prefers to observe his surroundings rather than actively engage, which can make him seem distant at first, but those who know him understand that his silence is a comfortable part of his personality. His gentle demeanor and unassuming presence lead others to describe him as a “quiet pretty-boy” who always stands by Jun’s side.

His main motivation is rooted in his deep bond with Jun and the rest of the band. He does not seek the spotlight for himself; instead, he finds fulfillment in supporting his friends and contributing through his music. As the bassist of High×Joker, he provides a steady, rhythmic foundation for the unit’s performances, blending his instrumental skill with the group’s energetic sound. Over time, his involvement in idol activities helps him gradually open up, building more confidence to express himself and interact with a wider circle of people. His growth is marked by small steps toward independence, though his core shyness and loyalty to Jun remain constant. Outside of his musical talent, Natsuki is known for his calm, observant nature, which allows him to read situations and people without needing many words.
