Mullin

Mullin has a sincere and straightforward personality. He is nurturing and always willing to help others.

His practical abilities as an attendant are so impressive that even Astaroth recognizes his competence.

Despite his strong work ethic, he lacks experience interacting with women except for his mother and his twin younger sisters.

Mullin is rather innocent when it comes to romantic matters.

He is quite naive and does not have much immunity toward members of the opposite sex.

This sometimes leads to awkward or flustered moments in his daily interactions.

At first, Mullin struggles with the differences between his preconceived image of Beelzebub and her true personality after becoming her attendant.

He is often confused and surprised by her behavior, which does not match his expectations.

Over time, Mullin gradually becomes enchanted by Beelzebub's genuine cuteness.

Witnessing her natural charm, he finds himself becoming increasingly drawn to her, sparking new emotions within himself.
