The Ephemeral Scenes of Setsuna’s Journey, Vol. 1 (light novel)

Setsuna Sugimoto is summoned to another world as the 68th hero only to be abandoned because of his weak and sickly constitution. But everything changes when he's given a third chance at life by his dear friend Kyle, the former hero, thereby inheriting his vast knowledge, power, and lifeforce. Freed from the tethers of his past, Setsuna begins a journey as an adventurer where he'll encounter all walks of life, each experience bound to leave their mark on both him and his world.
