Senyuu.

Long ago, the demon lord Rchimedes plunged the world into fear before being sealed by the legendary hero Creasion. A thousand years of calm follow—until a mysterious breach opens between the human and demon realms, allowing demons to pour into human territory once again. Convinced that Rchimedes’ return is imminent, a king gathers every possible descendant of Creasion: all 75 candidates, with no reliable way to confirm who truly carries the hero’s blood.

One of those recruits is Alba Frühling, an eager but inexperienced adventurer. Assigned to accompany him is Ross, a highly capable soldier whose sharp tongue and sadistic streak make him far less supportive than expected. Together, the mismatched pair sets off on a fantasy quest that doubles as a parody, as their journey to stop the demon lord keeps veering into chaos and comedy.
