The character Setsutei is a figure from the anime Ghost Concert: missing Songs, which is scheduled to premiere in April 2026. The available information about Setsutei is primarily limited to pre-release promotional materials and casting announcements, as the series has not yet been broadcast. Consequently, a comprehensive description encompassing personality, backstory, or character development is not available at this time.

Based on official cast and character listings, Setsutei is an adult male character distinguished by his physical appearance and occupation. He has black eyes and short black hair that reaches his ears. Visual tags associated with the character include stubble and a monk, suggesting that he may have a religious or ascetic background. He is often depicted wielding a staff, which is likely his primary tool or weapon. In terms of his role within the narrative, he is part of a broader cast that includes characters such as the protagonist Seria Aiba, the Great Ghost Cleopatra, and other individuals like Youtetsu and MiucS. The Japanese voice actor for Setsutei is Satoshi Hino.

Because the anime takes place in a dystopian 2045 where singing is prohibited and music is generated by an app called MiucS, the story involves psychic mediums from an organization known as TERA and a phenomenon called the Possession Requiem. While Setsutei is confirmed to be a part of this world, his specific motivations, his allegiance to any particular group, his relationships with characters like Seria Aiba or Youtetsu, and his unique abilities in the context of the series song battles remain unspecified in pre-release summaries. There is no detailed information regarding his personal history, narrative arc, or how his character might evolve throughout the story.
