Maylis Beelzenia was the Third Princess of the Beelzenian Empire and one of Duke Sateriasis Venomania's many victims. In response to the number of disappearing women in the Empire, Maylis employed several agents to investigate, including Count Karchess Crim, and tracked their progress. After one of her agents was seduced by Sateriasis, Maylis was also captured and added to his harem.


Early LifeEdit

Born in EC 114, the youngest daughter of Emperor Jupitaire Beelzenia, Maylis was spoiled by her father and grew up lavishly in the imperial palace as the Third Princess of the Beelzenian Empire. Around the time her brother Prince Martius was betrothed and married to Princess Yufina Marlon, Maylis and her siblings met the Marlon royal. She eventually began helping manage the empire's territories. At some point, she met Marquis Ferdinand and noticed the man lustfully stare at her during every encounter. She also met Baron Toy Conchita and developed a crush on him, making him her closest adviser.[1]

Ominous HappeningsEdit

"If it's feasible, it may be best you make your stay there as short as possible. It looks like that area is going to continue being dangerous..."
―Maylis regarding Asmodean[src]

Following the massacre of the Venomania household in December of EC 135 and the disappearance of Asmodean women in the subsequent months, Maylis opened a secret investigation into the matter. She then assigned Marquis Glassred to discern the cause and their whereabouts as the province's active governor, receiving regular reports from Toy regarding the case's progress.

When King Martius and Queen Yufina visited the imperial palace in March of EC 136, Maylis joined her sisters Febria and Aprilis in welcoming them in the throne room, immediately greeting Yufina. Seeing Yufina look unhappy with her husband, the young woman latched onto her arm and insisted she give her a tour around the palace. When the Queen rejected, citing they were in the middle of a meeting, the princess countered that they didn't need to stay with the "pig conference". After Martius and her eldest brother Janus agreed to allow it, the princess insisted they leave again and Yufina finally complied.

After they left, Maylis skipped ahead wondering where they should go first when Yufina suddenly thanked her. Once the Queen pointed out she noticed her discomfort, Maylis admitted she might've felt it before approaching the woman and noting her clear displeasure with Martius. As Yufina explained she didn't hate him, Maylis playfully warned her not to say that aloud before musing that arranged marriages were women's lot in life and that she too would probably be married off one day.

Yufina then hesitantly asked if she liked anyone and the embarrassed princess wildly waved her arms and played with the tips of her hair while fervently denying it. After saying she wasn't that popular anyway, the princess changed subjects to leave when Toy called out to her and turned to speak with him. Wondering what was wrong, the Baron confirmed it was another report for the investigation when he abruptly stopped and looked at Yufina. The princess told him to ignore her and listened while Conchita reported Marquis Glassred had gone mad.

Shocked, she heard him explain the marquis' household was massacred and his daughter disappeared and that they would likely need someone to replace him with his recent breakdown. Recalling Glassred was the active governor, Maylis inquired about the Asmodean citizens and Toy confirmed the new Duke Venomania would likely want to take over his original duty since he'd recovered. As Maylis considered the events, Baron noted they should rely on the Duke given the disappearance affected his territory.

The princess began noting the similar massacre of the Duke's family and the convenient circumstances since his recovery when Toy asked if she suspected a connection. Maylis asserted she at least believed there was, putting a hand on her cheek while considering their next course of action. Once the Baron suggested Marquis Ferdinand, the princess admitted she disliked him due to his constant ogling. Toy then pointed out he would act in secret from her siblings and she reluctantly agreed, entrusting him to arrange it.

After Toy left, Maylis looked back at Yufina and asked about her future plans in Beelzenia. Told she'd be touring the country to greet the Five Dukes in a few days, confirming that included Asmodean, Maylis realized she couldn't afford to cancel it. After advising she keep her visit there as short as possible due to the recent danger, Yufina agreed to consult Martius about it as well. The princess then happily questioned where they should go and the Queen allowed the playful princess to show her around the imperial palace.[2]

Venomania EventEdit

"Heheh... this has become quite the intrigue, hasn't it?"
―Princess Maylis[src]

In EC 136, at Toy's recommendation, she called upon Count Karchess Crim of the Kingdom of Marlon to continue this investigation.[3] Around the summer of that year, she sat in the throne room and listened to one of the ministers report his findings on the disappearances, describing his failure to actually find any of the missing women. She then noticed Toy enter and confirmed he had a report from Karchess. When the baron suggested reading it to her, the princess insisted on reading it herself, commanding the minister to leave before assuring him she'd read the rest of his report later.

She then read through the Count's report that he'd found a source indicating Duke Sateriasis Venomania was abducting the missing women. The amused princess chuckled before noting how interesting the situation had become before rolling up the letter and turning away from Toy. Putting a hand to her chin, she pondered slipping out of the palace to confront the Duke directly.[4] At some point, she dispatched a spy, Neruneru Nerune, to look further into the matter.

Later that year, she encountered and was enchanted by Duke Venomania. Seduced, the 22-year-old joined his harem of abducted women, satisfying Venomania's every whim and pleasure. At some point, she became pregnant with his child.[5] When the disguised Karchess successfully stabbed the duke, Maylis broke free of his spell and began to flee the mansion with the others.[6]

Later LifeEdit

Soon after, she discovered her pregnancy and the imperial family covered up the issue. While her family demanded she abort the child, Maylis refused. Once her daughter was born, Emperor Jupitaire refused to include the baby as part of the family. Because his wife was unable to produce offspring of their own, she gave the baby to Toy to raise as his own and the Baron accepted the child.[7]


"At any rate, I didn't expect you to have a relationship with him."
"Heheh. Well, he isn't the likable type."
"Do you—do you love him?"
"I hate him. I despise him."
―Allen and Maylis[src]

Following her death, Maylis was sent to the Heavenly Yard and remained there with her family and friends;[8] at some point, she heard tales of her later descendants such as the cannibal Banica Conchita.[9] In EC 998, she and the other souls were pulled back to the Third Period as the ground world merged with the Hellish Yard.[10] Afterward, the conflicted princess returned to Duke Venomania's mansion in Lasaland and agreed to rejoin Sateriasis' harem along with Mikulia, Gumina, and Lukana.

While attending to Venomania at his throne, the group noticed a boy walk in on them and the harem girl watched curiously as "Irregular" and the duke conversed. When the boy later tried to approach Maylis and Sateriasis chastised him for trying to approach his harem women, Maylis countered that it wasn't nice to throw needless tantrums; smiling, she approached "Irregular" herself and told him to forgive the man for his poor temperament.

When the boy asked if she was Maylis, the princess expressed her surprise that he knew her and said he was quite knowledgeable. Told by the boy to call him Allen instead, Maylis asked Allen what he wished to talk to her about. When Sateriasis called over to Maylis and asked what she liked about the boy, the former princess insisted it wasn't like that, citing she was just sick of how he was treating their guest; as the Duke continued to protest, she warned him that she would leave if he complained, silencing him.

Afterwards, as Allen asked why she wasn't in Beelzenia, Maylis made a lonely smile and explained how she met Sateriasis after being pulled down to the Third Period. Citing he was just elated with the situation, she reiterated that the boy should forgive his rudeness. As Allen continued to express his surprise that she had a relationship with him, Maylis agreed that he wasn't the likable type. Asked if she loved him, the former princess flatly clarified she hated him.

She then elaborated that her feelings on the matter weren't so simple, eventually supposing it was due to his relation to her daughter. Allen begrudgingly agreed and she finished with the statement that it was human nature for some feelings to not coincide with a person's behavior. Questioned if the other women felt the same, Maylis admitted she didn't know before adding that she felt Lukana and Mikulia really were in love with him while uncertain about Gumina's feelings for the duke.

As Allen finally prepared to leave with the demon, Maylis asked if she should call the other women for him and the boy gently refused, citing he lacked the time and already received the insight he needed. She then inquired where he would go afterward and learned his next goal was Banica Conchita; remembering the stories, Maylis shivered and told him to take care.[11] Some time after Allen left, the Master of the Hellish Yard visited and took Venomania back to the bowels of the Hellish Yard.[12]


Maylis and the Duke's resulting bloodline survived as part of the Conchita family,[13] eventually producing Banica Conchita, who later became famed for her contributions to Beelzenian culture and society as both "Gourmet Noble Banica" and "Evil Food Eater Conchita". Another one of her descendants from Banica, Germaine Avadonia, eventually led the Lucifenian Revolution and was heralded as a hero.[14]

Personality and TraitsEdit

Maylis was a playful but nonetheless earnest princess. Always looking into things that caught her interest for her amusement, she still took dangerous matters seriously and was resolute to solve them. Otherwise, the princess had very little motivation with her responsibilities as princess. Knowing she was her father's favorite child, Maylis usually ignored proper conduct and social etiquette with family, though still taking a formal manner in meetings with strangers.[15] Outgoing, enthusiastic, and childish, she looked at even serious matters as a game, enjoying being part of the adventure.[16]

Despite her obvious beauty, Maylis didn't believe she was really popular with men and disgusted by those who did notice her sex appeal. Maylis was infatuated with Baron Conchita and greatly embarrassed when the subject of her crush was even brought up. As a result, she enjoyed his company and made the effort to act more polite and professional with Toy.[17] At the same time, she took his advice into careful consideration and trusted his judgment. However, she still respected the fact he was married and kept her feelings to herself.[18]

Skills and AbilitiesEdit

A shrewd princess, Maylis took advantage of her resources effectively and her curiosity helped in her dedication to the disappearance cases. Willing to take advice from others, Maylis was unbothered by bringing in the foreign Karchess Crim to the investigation on Toy's recommendation. However, she also displayed naivety, trusting too greatly in Neruneru without considering an ambush and, like the other women, became helplessly enthralled by the Duke.[19]

Character ConnectionsEdit

Sateriasis Venomania: Maylis' abductor. Maylis fell in love with the duke due to the powers of Lust. After Karchess killed the duke, his power over her was broken and she fled, horrified by his exploitation of her. She looked back on their relationship with revulsion, maintaining her hatred well into her afterlife. Despite this, Maylis still loved the child she sired with him and, paradoxically, decided to stay in his harem when the Hellish Yard merged with the Third Period.

Toy Conchita: Maylis' minister and her personal love interest. Maylis had a romantic interest in Toy and maintained a close relationship with him, believing he was best suited for taking care of her unaccepted child. She held a high opinion of his judgment, initially assigning him to investigate the women's disappearances and later calling on Karchess at his recommendation.

Yufina Marlon: A friend of Maylis'. Maylis took a quick likening to Yufina, sympathizing with her disinterest in her brother Martius and relating to her plight with the knowledge that she too would be arranged to be married off one day. As such, she was concerned for the queen's welfare as she toured to meet the Five Dukes and wished her well before her kidnapping.

Karchess Crim: Maylis' agent. Maylis trusted Karchess with investigating the disappearances of the women in Beelzenia due to Toy Conchita's recommendation, however she expressed disinterest in his later results.

Neruneru Nerune: Maylis' spy and later fellow member of Venomania's harem. Maylis relied on Nerune to deliver more reports about the missing women before she was seduced, and their connection eventually led to Maylis' own abduction.


Conceptualization and OriginEdit

  • Maylis' name is derived from the month of May, the fifth month in the Julian and Gregorian calendars; Beelzenia, Maylis' native country, is partially inspired by the Roman Empire.
  • Her name is partially inspired by the name of her representative Vocaloid, MEIKO, with Maylis' romanization containing "Mei".
  • Her surname, Beelzenia, is a reference to Beelzebub, the patron demon of Gluttony.


  • Ironically, although unable to enter a relationship with the married Toy, the baron ended up raising Maylis' child due to his wife's inability to produce one of her own.[20]
  • Maylis' daughter was one of the three offspring of Venomania to carry the potential to develop Hereditary Evil Raiser Syndrome and pass it onto future generations.[21]
  • A Freezis Fairy Tale inspired by Duke Venomania is titled "The Duke and the Four Women", likely a reference to Lukana, Mikulia, Gumina, and Maylis' prominent appearance with Sateriasis in various media.
