Sven Vollfied

Sven Vollfied is the main character in the anime "Black Cat", a former IBI detective turned sweeper and partner to Train. He takes Eve in as a daughter after the events at Torneo's place. Sven's calm and logical demeanor contrasts with Train's more impulsive nature, often relying on his intellect in battles since he lacks Train's raw physical power. His Forseeing Eye, hidden under an eyepatch, allows him to glimpse into the future at a great mental cost, and it eventually evolves into the Glasper Eye, which can manipulate time.
