Maybe the male OC is a time - traveler. He accidentally lands in the world of Rosario Vampire. He has knowledge of future events which he uses to his advantage. He tries to prevent a big disaster from happening in the school. His presence also disrupts the relationships between the existing characters as they try to figure out who he is and what his motives are.
One idea could be that the male OC is a new student at the school. He has a special ability that he tries to hide at first. But as he gets to know the characters from Rosario Vampire, he gradually reveals it. For example, he might be able to control shadows and uses this power to help his new friends in a dangerous situation.
The male OC could be a half - vampire half - human. He comes to the Rosario Vampire world seeking a cure for his vampiric side. Along the way, he meets Moka and the others. He has a conflicted personality because of his two natures. He might struggle with his thirst for blood while also trying to fit in with the human students at the school.
