Ken Robbins  

Ken serves as the stage manager for Kaleido, but due to a heart condition, he's unable to perform. He has strong feelings for Sora and greatly admires her, yet he lacks the courage to confess his love. In one episode, he mistakenly declares his affection to her, causing Mr. Policeman to misinterpret him as a fan. Despite this, Ken continues to support Sora by acting as her personal trainer, giving warnings about potential dangers and serving as the voice of reason for the group on multiple occasions. Anna is set on making Ken her partner in comedy, but he's not interested.
