Manic, cunning, and unstable. "Dean", a restless berserker, was once a demi-God. A fierce warrior with an ability to conjure thunderous electro magic, he was known as "The Son of Raiden". Sadly, he failed to protect, not just his friends, but also his lover and his parents from a man calling himself "the better son of Raiden". Blaming himself for his failure, losing those he loved, became a lunatic both in physical and mental sense, turning his kind-hearted soul into a murderous psychopath. Now he's on a pilgrimage to avenge his comrades and family, a violent-tempered being seeking redemption for his own failure, and hoping to forgive himself and restoring his own humanity.
