Laios is a supporting character in the spinoff sequel The Dawn of the Witch.

Spoiler

He is a human who lives with his mortal parents in the village, where Zero and Mercenary dwell. He was one of dozens of villagers who stayed home to complete the test that was made for Saybil, Kudo and Hort. He has befriended Saybil, despite getting hurt by a rouge Remnant of Disaster while with the high sorcerer-in-training.

He is caring and somewhat naive of his parents' fear and distrust of those who practice sorcery or magic.
