Mullin meets a new girl, Eurynome, in a meeting, but every time their eyes meet, she gives him a look of complete disgust. Mullin’s worried that Eurynome hates him for some reason, but he finds out the real reason. Later, Mullin wins some movie tickets, and ends up promising to go with Beelzebub, but things don’t quite go as planned.

Mullin visits the Pandemonium Library along with Azazel and runs into the sleepy bookworm, Dantalion, as well as the ancient demon, Moloch, who always tends to talk in a loud voice. Later, Belphegor​ wants to come up with an excuse to talk to Azazel, so she starts making brownies with Beelzebub.

Beelzebub breaks her heels on her way to the office. Adramelech, Pandemonium’s advisor of all things fashion, vows to fix the heels, and we learn just why Beelzebub insists on wearing high heels in the first place. Later, Beelzebub does an interview with a Pandemonium magazine, and we learn a bit more about her likes and dislikes...

The members of Pandemonium are not getting enough exercise, so they decide to build a gym, but when it comes time for the opening ceremony, Beelzebub and the others find themselves staring at a Japanese-style bath instead. Since the facility already exists, they might as well get in… Later on, Beelzebub learns more about Mullin and the pet he keeps at home.

Sargatanas loves the characters from Fluffy Whiskers & Friends. The show and a cafe are doing a joint colaboration together, and Sargatanas would love to go. The only problem is that it’s too cute, and she doesn’t think she’d fit in. Later on, Beelzebub and Belphegor make plans to go to the beach, and ask Adrammelech to help them pick out swimsuits.

Mullin jokes that he might put in a transfer request and Beelzebub takes it pretty hard. Mullin gets worried that he might have upset her, so he goes to Astaroth for advice. Meanwhile, Belphegor can't help but run away when she sees Azazel. Belphegor wishes she could tell Azazel how she feels, but just can't work up the courage, and that's when she runs into him in the library...

Astaroth's always slacking off, not doing his work, and messing around with girls. As always, Sargatanas heads off to find him. After wrangling him in, they stop by a park, and Sargatanas suddenly finds herself having to face her feelings towards Astaroth. Later, a cold front descends upon Pandemonium, but Beelzebub can't handle the cold very well. Mullin and Beelzebub try various things to keep her warm, but Mullin comes up with one last idea...

One day at a tea party, Belphegor accidentally drinks alcohol and falls asleep. Azazel finds her, panics, and goes to look for help. But then a sleepy Belphegor pulls him back...

Part A: The sweater that Beelzebub had gotten from Mullin that she liked so much starts to come undone. Beelzebub is in so much shock that she keeps sighing and trying to avoid eye contact with Mullin. Mullin misunderstands and feels like he made her upset again somehow... Part B: Beelzebub have a flower viewing party now that spring is here. Beelzebub says that she’s never being to a flower viewing party, so the others go all out for her. Since the day is so chill, Mullin happens to remember when he first became Beelzebub’s attendant...
