Adventurers' Guild staff.

Rentt was supposed to introduce Lina as her mentor, but since Rentt went missing (actually turned into a monster), Lina had to be sent into the dungeon alone.

Due to information received that Rentt, who was hiding his face, was the perpetrator of some incident, he was ordered by the guild master to act as a surveillance officer.

He had a vague suspicion that Rentt Vivie was Rentt Faina, and under a magical contract, he agreed that if he disclosed the secret, he would resign from the guild and become Rentt's slave, and he learned that Rentt had become an immortal monster and that Lorraine was involved.
