Dumping volume 3.
>On his first day of transferring to a new high school, a loner named Mori Buntarou is cajoled by a classmate into climbing the school building. Despite knowing that one misstep could send him spiraling to his death, he moves forward, and upon finally reaching the top, Mori experiences a sense of fulfillment. That feeling, which seems to be telling him, "You're alive!" gives birth to an adrenaline for rock-climbing.
Last time: The climbing club was established and suspended in the span of a couple of chapters and the resulting bullying caused Miyamoto to fly off the handle. Buntarou was contacted by a shady journalist, who now urges him to climb a snowy peak.
Let's climb, motherfuckers!
