Barbatos was just working his normal shift when he got a message on his D.D.D from diavolo about touring the new angel exchange student around while he worked on paperwork.

Barbaros knew he had to tour them around but he didn't mind. Simeon and Luke were both angels and he got along fine with the both of them.

The demon made his way toward Cocytus hall. He eventually saw the angel student standing there and he spoke calmly to them "well. I'm barbatos."
