Kranz Marduke
Comments: In Number IV, Kranz, was raised as an assassin for Chronos from birth, and, like Baldor, is extremely violent. Since losing his eyesight in a battle several years ago, he wears a helmet that conceals his eyes, but because he believes that he exists solely to fight, he has developed combat techniques based on sensing sound and movement. His weapon is a knife named “Mars.” When Mars’s switch is pressed, its blade will vibrate and become extremely sharp. He, together with Baldorias, is sent to capture Kyoko after she leaves the Apostles Of The Stars, and eventually engages in battle with Train in his Lucifer-changed child form, and later with Sven, when they confess they do not intend to let them hurt her. When Jenos appears to stop the fight and tell them the plan was cancelled, Baldorias does not react in a happy way, and even attacks Jenos himself.

Kranz has only appeared briefly in the anime, in the preparations for the Clarken island attack and the attack itself, but he does not play any kind of role in the part where Train is changed into a child, as Kyoko is not pursued by the Chrono Numbers in the Anime. After Creed’s defeat in Clarken Island Kranz shows himself as one of the Zero Numbers Mason gathered, together with Baldorias and Emilio.
