Hayato Kidokoro starts as manager for established idol Megumi Ayase at Parthenon Productions. His role shifts dramatically when reassigned to oversee rising star Creamy Mami’s career.

Kidokoro’s management style fuels constant comedic mishaps, triggering chaotic production issues. His logistical blunders—like mistakenly transporting Creamy Mami to a remote island instead of her concert venue—routinely endanger high-stakes events. These errors often provoke sharp reprimands from company president Shingo Tachibana, particularly when causing Creamy Mami’s delays or operational disruptions.

This pattern of generating misfortune extends to spin-off media, preserving his narrative function. Kidokoro operates strictly within the idol industry’s human professional realm, never engaging with supernatural elements or displaying magical abilities.

Across television episodes, original video animations, and manga adaptations, his portrayal remains uniform. He consistently delivers comedic relief through professional missteps and drives plot complications via managerial ineptitude.
