The Climber, Vol. 1 by Shin'ichi Sakamoto

A withdrawn young man becomes consumed by the art and danger of solo mountain climbing, and the volume tracks his transformation as climbing shifts from hobby to an all‑encompassing obsession; through precise, often brutal depictions of technique and endurance, it explores how solitary ascents become a means of testing limits, confronting fear, and carving out an identity even as they isolate him from ordinary life and relationships.
