After Claude the demon king's marriage to Aileen, Belzebuth continues to work as Claude's bodyguard. This time he was given time off for work, actually he refused the offer but Claude still gave him time off and he was forced to accept it.

He was at the human market and was walking around to see what they were selling. He accidentally bumped into a girl carrying her groceries and fell over.

So beautiful, he thought while helping the girl. Here, sorry I accidentally bumped into you.
