Arisu

A young priestess who leads a small group of demons that worship Ishtar, the goddess of darkness, on a pilgrimage. While being confronted by the three heroes, she enacts a plan to resurrect an ancient Demon King who will bring salvation to the cornered demons.

After Demon King Rhegius' resurrection, she is appointed as one of his advisors while also becoming the Head Priest under Ishtar. A highly prized civil servant, she sometimes faints due to the devilish behavior of the Demon King. She is a kind girl who is beloved by the people of the demon nation Zigrad.
