A major character from Tsukihime. The unofficial 28th of the Twenty-seven Dead Apostle Ancestors, nicknamed The Serpent of Akasha and The Infinite Reincarnator, he's the antagonist and the root of the chaos in the story.
The eternal nemesis of Arcueid Brunestud and Ciel, he became a dead apostle for the sole goal of "seeking eternity" to obtain infinite knowledge beyond his human lifespan.
Roa's form varies upon the body he is currently inhabiting, but he is able to change it to some degree to suit his preferences.He's commonly seen as a young slender male, with flowing long black hair and red eyes. Almost always seen wearing an white open shirt that reveals his torso. Sometimes wrapped in bandages.
In Tsukihime Remake, he changes his long hair to a slicked back one instead.
