Mitsuo, a second-year in Class 2-A at Sanada North High, embodies perpetual misfortune tempered by unwavering kindness. His gullibility and naivety make him a frequent target of ridicule, often blamed for mishaps rooted in others’ histories—like Yoshitake’s childhood blunders. A childhood prank by Motoharu, swapping his shoes with a girl’s unnoticed until graduation, epitomizes his lifelong streak of unwarranted embarrassment. Even his altruism backfires, such as diving into a river to “save” a stuffed cat, a hallmark of his comically tragic existence. Unremarkable in stature with tousled dark brown hair and brown eyes, Mitsuo’s unassuming appearance in standard uniform belies a timid, jumpy demeanor. Yet beneath his skittishness lies unexpected athletic grit: once a disheartened soccer player, he shifted to rugby after a missed goal against Hidenori, later showcasing strength by fending off multiple attackers or toppling Motoharu with a precisely hurled marble. Quirks like a hidden adult magazine collection or a kiwi-stuffed mouth incident—ending in itchy distress—add layers to his hapless persona. Non-canonical fan expansions place him in alternate roles, like AWA Academy student or DreamTheater Intermix participant, though these diverge from his core narrative. While peers exploit his credulity for humor, casting him as the group’s punching bag, Mitsuo sporadically defies expectations. Moments of physical prowess on the rugby field or sudden assertiveness puncture his bumbling facade, hinting at latent capability beneath the chaos. His resilience persists—a gentle soul weathering endless mockery, yet enduring with quiet, if bemused, perseverance.
