–Marius introducing himself to the Occult Research Club, Volume 16, Life.1 Occult Research Club, to Romania!


Marius Tepes was a pure-blooded Vampire prince of the royal family of Tepes and a member of the Tepes Faction, a Male-dominated Vampire faction. He was the second son of the 4th King of Tepes, the younger brother of the oldest son, and the older half-brother of Valerie Tepes. He was fifth in line to succeed the throne.


Marius Tepes was a young man with a beautiful face like a doll. He was older than his sister Valerie.


He appeared to be calm and mannered, but was actually a cruel and evil individual controlling his own sister for his own benefits and even went as far to ask his own father and brother to leave as they were a nuisance to him.

He was quickly shown to become a coward when he realized that the Holy Grail was unable to protect him from Gasper's power.


Marius was one of the sons of the 4th King of Tepes and the fifth candidate in succeeding the throne. After Valerie activated her Longinus, Marius started doing various research on the Holy Grail, forcing Valerie to overuse the Grail to the point where she suffered a mental breakdown. During that time, he had made contact with Rizevim Livan Lucifer, who helped Marius in his research in exchange for reviving the Evil Dragons. Afterwards, Marius created a coup d'état along with many members of the Tepes Faction and chased his father and his brother away.
