Chisato Mera, a female student at PK Academy born April 15, stands 1.60 meters tall with auburn hair, red eyes, and blood type A. Weighing 48 kilograms, she juggles academic responsibilities with multiple part-time jobs, her diligence and determination starkly contrasting her financial hardships. Chronic exhaustion from relentless work fuels her insatiable appetite, driving her to scavenge for snacks with resourceful urgency—a testament to her pragmatic survival instincts. Her personality marries selfishness and tactlessness to an unexpectedly good-hearted core. Moments of desperation reveal a greedy streak, like accepting dubious substances from untrustworthy sources, yet her actions remain rooted in unapologetically practical choices. Clumsiness occasionally disrupts her efforts, but tenacity steers her through challenges. Blunt and efficiency-driven, she dismisses social decorum, casually admitting to risky behaviors such as eating wild mushrooms without hesitation. Though her background remains sparingly detailed in official media, her narrative consistently spotlights resilience amid adversity. She navigates a precarious equilibrium between work, studies, and personal needs, embodying a flawed but grounded response to life’s pressures. Without major arcs in spin-offs, she endures as a secondary character whose comedic yet relatable struggles underscore themes of perseverance within the series’ everyday chaos.
