Description
Beelzebub Zebul is the Archdemon of gluttony and the father of the protagonist, Kanan, in the romantic comedy anime Mistress Kanan is Devilishly Easy. As a high-ranking noble from the Demon Realm, his title and domain are directly tied to the sin of gluttony, a fact that influences his role as both a powerful figure and a concerned parent.

In terms of personality, Beelzebub is defined by his deep, genuine love for his daughter. He is portrayed as a caring and attentive father who worries about Kanan's well-being, specifically her emotional state. His concern stems from the observation that his daughter had started eating alone and lost her sense of joy in food, a troubling development for the Archdemon of gluttony’s own family. This sadness, described as a sense loss, motivated him to allow Kanan to travel to the human world, hoping she would rediscover her love for eating.

Beelzebub’s primary motivation throughout the story is his daughter's happiness. He is overjoyed to learn that Kanan has begun to enjoy meals again after starting her relationship with the human boy Yoji Kyogi. However, this joy is tinged with a subtle jealousy, as he had hoped to be the one to reignite her passion for food. When it comes to Kanan's romantic life, he plays the archetypal protective father, though his actions are more playful than genuinely obstructive. Upon meeting Kyogi, he performs the cliché of shouting that he cannot accept the young man as his daughter's boyfriend, only to admit he simply wanted to say the line. Despite this, he does express legitimate apprehension about a relationship between demon nobility and a human, citing concerns about appearances and social station. To test the strength of their bond, Beelzebub sets the couple a challenge: to receive the approval of all five members of the Zebul family in the form of a stamp rally, which becomes a central goal for the characters.

Beelzebub’s role in the story is that of an authority figure and a catalyst for the main couple’s development. As the patriarch of the Zebul family, his approval is the final and most significant hurdle in the stamp rally challenge. He is not an antagonist but rather a loving father who wants to ensure his daughter’s partner is worthy. His actions, such as sending the family maid Ami to the human world to check on Kanan, stem from a place of concern and care, even if they inadvertently create comedic situations for the protagonist.

His key relationships revolve around his family. His bond with his daughter, Kanan, is the most defining aspect of his character. He is a good parent who supports her journey and wants her to be happy. His relationship with Kyogi is initially one of wariness and testing, but it is rooted in a desire to see his daughter with a suitable partner. He is also the patriarch of the Zebul family, and his interactions with its other members help establish the dynamic of the demon household.

While the anime does not focus heavily on Beelzebub’s personal development, his perspective shifts from passive observation to active involvement in Kanan’s life. His character serves to provide the overarching family approval plot that drives the story forward. Information on his specific demonic abilities is not detailed in the source material, but his status as an Archdemon implies a high level of power within the hierarchy of the Demon Realm.
