Lore & Background

Mitsuru's descent begins within the glittering but cutthroat world of B-Kitchen. While publicly adored as a talented member, his internal world was fractured by an intense, unhealthy fixation on Ai Hoshino and her son Aqua. Unlike other rivals who sought to surpass the group through hard work or strategy, Mitsuru's approach was rooted in emotional volatility and a desire to control the narrative of fame.

His actions were not merely competitive but deeply personal, blurring the lines between professional rivalry and stalking behavior. This obsession led him to make reckless decisions that jeopardized his reputation and safety, ultimately forcing him out of the idol sphere he once cherished. His story serves as a cautionary tale about how the industry can warp an individual's psyche when fame becomes an all-consuming addiction rather than a craft.

In Their Own Story

The stage lights hummed with a heat that felt less like electricity and more like a fever. Mitsuru stood in the wings, watching Aqua perform with a smile that didn't reach his eyes. To the audience, it was a moment of youthful camaraderie; to him, it was a battlefield where every note sung by the boy was a challenge he couldn't ignore. He gripped the velvet curtain until his knuckles turned white, whispering promises to himself that he would reclaim what felt stolen. The applause washed over him, but all he could hear was the silence of his own crumbling future.

Reader's Guide

Mitsuru is defined by his tragic transformation from a talented idol into an obsessive antagonist. His arc highlights the psychological toll of the entertainment industry, specifically how the pressure to maintain relevance can lead to destructive behavior.

Initially, he appears as a capable member of B-Kitchen, but his true nature reveals itself through his fixations. He possesses acting skills and stage presence, yet these are undermined by his inability to separate professional ambition from personal vendettas. His defining moments involve direct confrontations with Aqua, where his actions escalate from competitive jealousy to genuine threats.

Ultimately, Mitsuru's story is one of lost potential. He represents the dark side of stardom, showing that not everyone survives the glare of the spotlight without being consumed by it.
