Souten no Ken Regenesis Episode 20, The Path of Kenshin Kasumi (霞拳心の道)

Official synopsis At Mount Koya where the sound of bells resonates, someone passes through the gate of the Hokuto temple. The one who appears before Tesshin, the father of Kasumi Kenshiro, is Kasumi Kenshin, who has renounced the name Himuka. Long ago, Kenshin, having fallen from a cliff and lying on the ground, had been rescued by Tesshin, and had trained under his guidance. What Kenshin reveals to Tesshin, facing him, is the burning desire for a new world, the path of re-genesis, born from the deep despair he once felt at what this world had become. "You have fallen so low, Kenshin..." A fighting aura emanates from Tesshin.
