- "Then that means applause are in order for your rule, esteemed brother Janus."

Martius Marlon, born Martius Beelzenia, was the second prince of the Beelzenian Empire and the third child of Jupitaire Beelzenia. He was married to Yufina Marlon as part of a political alliance with the neighboring kingdom. With the unexpected death of his wife's father, Martius assumed the Marlon throne as its sole male heir.

- ―Janus Beelzenia to Martius[src]
Martius was born during the turn of the second century EC within the Beelzenian Imperial Family, the third child of Emperor Jupitaire Beelzenia. He was later betrothed to Princess Yufina of Marlon to forge a political alliance between the two nations. As the couple prepared their wedding, the Five Dukes agreed to help arrange it and the two were married in a lavish ceremony.
During the period, Martius acquainted his wife with his siblings: Janus, Febria, Aprilis, and Maylis. When the King of Marlon suddenly died sometime after, the kingdom's parliament agreed to Martius succeeding his father-in-law as the only male heir while Yufina became his Queen.

"Well, it doesn’t look to have changed much to me, for good or ill."
- ―Janus and Martius[src]
In March of EC 136, King Martius planned to have a homecoming with his wife, deciding they'd stay in the capital of Rucolebeni for a few days before touring Beelzenia and meeting the Five Dukes for three weeks. Traveling to the port town of Jamet the day before their departure, Yufina briefly left Martius before returning later that day. The next day, the royal couple departed with their entourage on their ship and arrived in Beelzenia two days later, arriving in Rucolebeni over a week after that to have a meeting with Martius' siblings.
Once they entered the imperial palace's throne room, the royal couple was greeted by Janus and Martius made polite conversation with his brother, flattering his ego and joking with him until their other siblings arrived. He then allowed Maylis to give Yufina a tour at Maylis' request as the meeting, would be between him and his siblings.
The royal couple later toured the various regions of Beelzenia, with Asmodean being their last stop. Hosted by Duke Sateriasis Venomania, Martius discussed Sateriasis' father Ilotte with him, the two having been close in their youth. When the latter suddenly interrupted and asked how long they'd be staying in Asmodean, Yufina explained they would be staying the night at Marquis Marcs Donald's mansion in Lisa-A before departing back to Rucolebeni and then Marlon. The royal couple then excused themselves and left, with Martius reassuring him with being the local lord.
When Yufina later disappeared following the attack on the Donald estate, Martius frantically began searching for her, telling the public that she was too ill to return home. Martius eventually returned to Marlon due to the war situation. Overcome with grief, he began considering hiring Elluka Clockworker. When Count Karchess Crim hounded him over Yufina, he confessed that she had in fact been abducted in Asmodean.
After Karchess assassinated Venomania later that year, Martius ordered Karchess' arrest and hunted both him and Yufina throughout the year. When Karchess' new, "legitimate" Marlon country declared war on Martius' government two years later, the Beelzenian King of Marlon resisted before eventually being overthrown.
Personality and Traits
Martius was a gentle and unambitious man. Being amiable and kind towards practically everyone, Martius often acted subservient to those around him, especially when talked down to. He sometimes even slipped into a sycophantic praise for others' accomplishments despite his own impressive status. As a result of this excessive generous temperament, the man rarely became angry and maintained a happy disposition in almost any given situation.
Skills and Abilities
As the King of Marlon, Martius held complete dominion over the eastern half of the Marlon Island, though rarely using its authority. Regardless, because of his relation to the Beelzenian Imperial Family, the king had limited influence with his siblings and the Empire's resources at their disposal. Due to his obesity, he wasn't very physically able.
Yufina Marlon: Martius' wife. Martius trusted and cared for Yufina as his wife, taking care to treat her with respect and to never bring her to harm even accidentally. Despite this, he treated their relationship without any particular passion and did not even take the initiative to make love to her.
Maylis Beelzenia: Martius' sister. Although having a typical sibling relationship with Maylis, Martius nonetheless held contempt towards his sister for her more irresponsible attitude, particularly as their father's favorite child.
Conceptualization and Origin
- Martius' name is derived from the month of March, the first and later month in the Julian calendar; Beelzenia, Martius' native country, is partially inspired by the Roman Empire.
- His original surname, Beelzenia, is a reference to Beelzebub, the patron demon of Gluttony.
- Martius' later surname, Marlon, is a reference to Mammon, the patron demon of Greed.
