3,000 years agoEdit
Glariza was a member of the Demon Clan and in some point she became the lover of the wizard Gowther.
She was part of a group of innocent civilian Demons that were masacred by the Archangel, Mael. In her final moments, she asks for one final moment with Gowther.
Glariza is seen in Mael's memories, in which she is about to be killed by him.
Not much is known about their relationship, but even in her final moments, Glariza wanted to see Gowther once again, and it's implied that they loved each other very much. Her death at the hands of Mael led Gowther to choose him to replace Meliodas in the Demon Clan.
