Description
Hiroshi Yūki is a high school student with short black hair, dark gray eyes, and a distinguishing mole under his left eye. He wears his school uniform in reality. Within the virtual world of Kiwame Quest, his avatar "Hiro" sports a faded light-blue tunic over a long-sleeved black shirt, brown shorts, black stockings, and brown shoes.

Once a promising member of his school's track team, Hiroshi quit after a traumatic incident during a race where he tripped and publicly wet himself, leading to severe humiliation. This event soured his relationship with his previously admiring younger sister Kaede, who now views him with scorn and subjects him to verbal abuse. Hiroshi became directionless, cynical about reality—which he describes as "shitty"—and sought escapism in virtual reality MMORPGs.

Tricked into purchasing the ultra-realistic Kiwame Quest, Hiroshi discovered its mechanics directly mirrored his real-world physical and mental abilities, meaning he started unskilled and unfit. His initial naivety and frustration culminated in an accidental murder during a confrontation: he tackled his in-game childhood friend Martin, causing Martin to impale himself on a knife. This earned Hiroshi the permanent in-game title "Best Friend Killer" and triggered Martin's sister Alicia's descent into homicidal madness.

Hiroshi endures consistent physical and emotional torment both in reality, where he is bullied, and in Kiwame Quest, facing relentless adversity including torture sequences and public humiliation (such as wetting himself during an inquisition) and betrayal. His reactions to stress involve screaming, panic, and impulsive decisions, though he occasionally accesses a unique ability called "Adrenaline Rush," granting heightened speed in life-threatening situations.

Despite minimal initial growth, Hiroshi gradually develops resilience. His determination to complete Kiwame Quest stems partly from a promise of marriage from his guide, Reona, but evolves into a personal challenge. After his game console is destroyed upon an in-game death, he begins training in real life—resuming running—indicating a shift toward self-improvement. His final confrontation ends in defeat, but he gains a second chance to reset his progress, suggesting ongoing development.
