Vollfied, Sven

スヴェン＝ボルフィード

Sven, a former IBI detective, now works as a sweeper and serves as Train's partner. Following the incidents at Torneo's residence, he takes Eve in, treating her somewhat like a daughter. Sven's perspective is considerably calmer and more logical than Train's; lacking the Black Cat's raw physical strength, he frequently relies on his intellect to secure victories in combat. He adheres to a strict "gentlemen's code," which often leads other characters to perceive him as older.
The Forseeing Eye, concealed beneath his eyepatch, enables him to catch glimpses of the future, though this ability exacts a heavy toll on his mental state. In the manga, this power eventually develops into the Glasper Eye, granting him the ability to manipulate time. Aside from these abilities, he engages in combat using a briefcase stocked with various gadgets.
