Description
Shuta Aoi, nicknamed Shu, is the son of Tokyo's 24th Ward Aoi Bakery owners. His exceptional athleticism stems from daily workouts. Before the main events, he patrolled the ward as the vigilante "Mr. 24," protecting its streets and residents.

His life shifted dramatically after the Takara Elementary School fire one year prior. Rushing into the burning building, Shuta attempted to rescue Asumi Suido, younger sister of his childhood friend Koki Suido. He failed; Asumi suffered fatal injuries shielding another friend, Kozue Shirakaba, and died in his arms. This traumatic failure caused him to abandon vigilantism and focus solely on the family bakery.

A year later, during a memorial for the fire victims, Shuta and his childhood friends Ran Akagi and Koki Suido received a simultaneous phone call from Asumi's number. This call granted them ocular abilities to visualize imminent life-threatening events minutes before they occur. Their first vision presented a trolley problem scenario involving friend Mari Sakuragi and a runaway train. Shuta became convinced this proved Asumi's continued existence in some form, motivating him to use this power to prevent tragedies.

Shuta, Ran, and Koki are collectively known as "RGB" due to their distinctive hair colors (red, green, blue), reflecting their lifelong bond. During subsequent rescue missions, like intercepting the train threatening Mari, Shuta demonstrated near-superhuman physical capabilities. His actions are driven by resolve to avoid repeating his past failure and a deepening belief that Asumi's guidance offers redemption. He maintains close ties with others affected by the fire, including Mari, who also blames herself for Asumi's death, and Kozue, who stopped attending school post-tragedy.

The visions consistently involve moral dilemmas forcing immediate choices between conflicting outcomes, reinforcing Shuta's commitment to saving everyone possible. This resolve and his physical prowess position him centrally in responding to crises orchestrated by the mysterious entity Carneades within the 24th Ward.
