Natsuki Ishibashi

Natsuki Ishibashi is a character from Clock over ORGANY (CloORG), a Japanese multimedia project built around music, character drama, and battle-royale-style storytelling. Introduced as the first participant in the series and identified as number 01, he is portrayed as a gentle, polite presence within the project’s shifting hierarchy. His age changing between child, youth, and adult forms is one of the series’ most distinctive design traits, and it helps give Natsuki a memorable place in the project’s emotional worldbuilding. Music is central to Natsuki Ishibashi’s identity, and his songs are written to reflect that narrative focus. His primary theme, "Kimi ga Inai Sekai de" ("In a World Without You"), was produced by Scop and combines pop-rock and alternative elements with an emotional, character-driven approach. In Clock over ORGANY, music is not simply an accessory to the story; it helps define each participant’s inner conflict, and Natsuki’s releases are part of that larger dramatic structure. That connection also makes Natsuki especially relevant for listeners who follow seiyuu-driven character music and music-focused multimedia projects. The character is voiced by Japanese voice actor Kouhei Amasaki, whose performance gives him a youthful but composed tone that fits his changing forms. Amasaki is also known to fans of Hypnosis Mic and Ensemble Stars!, which adds another layer of recognition around the character. For fans searching for Natsuki Ishibashi’s role, voice actor, or age-related details, he remains one of the most distinctive figures in Clock over ORGANY. His combination of soft-spoken personality, unusual age progression, and music-led storytelling gives the character a memorable place within the project. That blend of performance and narrative identity is a major reason Natsuki continues to attract attention from anime and character-song audiences.
