Set in the Enryaku-ji Temple on Mount Hiei in the late Edo period, this novel follows two Buddhist monks who undertake the grueling Sennichi Kaihogyo, a thousand-day mountain walk where failure means death. Though both master Jisho and disciple Kaien share the same secret of imperial lineage, rather than joining forces, they clash fiercely against each other. A full-scale historical entertainment novel that blends meticulous research into monastic life with raw human emotions of desire for recognition and hatred.

Death or immortality. A blazing human drama of monks who stake their lives on a grueling spiritual ordeal.
