Akira Tendō, a 24-year-old former office worker, survived three years of grueling exploitation at a ruthless black corporation, culminating in severe mental and emotional collapse. Enduring unpaid overtime, chronic sleep deprivation, and psychological abuse under tyrannical supervisor Gonzou Kosugi, he teetered on the brink of suicide until the zombie outbreak unexpectedly becomes his liberation. The catastrophe rekindles his childhood optimism, spurring him to draft a "bucket list" of 100 aspirations to reclaim life’s joys before potential zombification. Standing 170 cm with a rugby-forged athletic frame, he sheds his formal office wear for practical, casual clothing post-collapse, accessorizing with goggles or temporary dreadlocks for specific list entries. His physical stamina and agility—honed through years of tackling opponents—prove vital for evading hordes or surviving perilous leaps. Later, he adopts a modified shark-proof suit for close-quarters combat, capitalizing on its bite resistance while remaining cautious of its vulnerability to blunt force. Guided initially by a childlike zeal, he prioritizes whimsical personal fulfillment over pragmatic survival—chasing cold beer or confessing long-held crushes despite the risks. Social interactions expose a mix of earnestness and social clumsiness, particularly around women, though he maintains respectful supportiveness. Key bonds include Kenichirou "Kencho" Ryuuzaki, his college-era friend and wisecracking counterpart; Shizuka Mikazuki, a fiercely pragmatic survivor whose guarded pragmatism gradually thaws into mutual respect and affection; and Beatrix Amerhauser, a German Japanophile who allies with their group. Traumatic losses—such as witnessing the deaths of admired coworker Saori Ohtori and Yukari, a flight attendant he connected with—compound his emotional layers. These tragedies, paired with repeated clashes against his zombified ex-boss, compel him to face lingering trauma while solidifying his resolve to live authentically. A reunion with his parents in Gunma Prefecture reveals his father’s deteriorating health, driving him to scavenge medical supplies and aid vaccine development. His bucket list transitions from playful pursuits (racing a Harley-Davidson, devouring *Romance of the Three Kingdoms* in one sitting) to soulful objectives like rebuilding familial ties and nurturing community bonds. Though occasionally faltering into self-absorption or dread, his unwavering spirit inspires companions to craft their own hopeful agendas. His growth peaks when rejecting Kosugi’s spectral taunts, breaking free from corporate-brainwashed obedience to declare self-determined purpose.
