Roa is a vampire known as the "Serpent of Akasha" or the "Infinite Reincarnator." Former priest of the Holy Church. He can manipulate information and electricity at will. The story of Roa appearing in Souya that came to him predicts the possibilities he might have had following a chance encounter with Arcueid and Shiki.

He loved people, not as humans, but as a collective, and so resolved to record their deeds. One day, he realized he lacked the time to record everything, his life too short to satisfy his need to learn and know everything. The more he continued his work, the more his despair grew. As a result, he decided he needed to become eternal by becoming a vampire. The reason why he chose to reincarnate endlessly is not that he sought power, but simply to continue being, until the world comes to a close. When Shiki asks "if the world is infinitely expanding, surely the priest's goals are misplaced?" Roa replies that "humans were placed in the universe to define it, if not, why where they given intelligence?"

At some point his objective changed. He who had sought eternity for the sake of completeness, had his purity robbed of him. He saw the "Princess", believing it was all her fault. He wanted to continue living, not as an observer, but as someone a part of the events. But those pure feelings were all washed away in face of her.
