On his first day after transferring to a new high school, Buntarou Mori is challenged by classmate Masao Onishi to scale the exterior wall of the school building. What begins as a reckless stunt to test a sullen loner turns into an awakening. Free climbing the drainpipes and masonry without ropes, Mori reaches the roof and experiences a terrifying clarity absent from his mundane social existence. English teacher and veteran climber Toru Miyamoto identifies Mori's raw spatial awareness and grip strength, guiding him into formal bouldering and alpine ascents.

Mori rapidly outgrows school competitions and standard climbing clubs. While conventional mountaineering relies on teamwork, roped partners, and shared logistics, Mori feels suffocated by interpersonal friction, social obligations, and peer deceit. He gravitates toward solitary climbing and winter soloing in the Japanese Alps, where self-reliance is absolute and a single misjudged hold guarantees death. His fixation culminates in an ambition to conquer the unclimbed East Face of Mount K2 during winter, pitting his psychological endurance against frostbite, crevasse falls, and the hallucination-inducing thin air of the death zone.

What to Expect

The narrative shifts from a grounded high school sports dynamic in its opening chapters to an unsparing psychological character study. Shinichi Sakamoto's visual direction strips away standard manga conventions, utilizing surreal, metaphoric spreads—such as frozen cityscapes, decomposing wildlife, and suffocating blizzards—to represent Mori's internal isolation. The pacing mirrors real mountaineering: meticulous preparation, route assessment, and physical gear management juxtaposed against sudden, lethal emergencies where mistakes are irreversible.
