–Magnus introducing himself to Rias Gremory, True Volume 4, Life.2 — And then to the Kingdom


Magnus Rose is a CIA agent, and the possessor of the Longinus: Unknown Dictator. He is currently a member of Team Phoenix for the Azazel Cup.


Magnus is described as a muscular Caucasian man with a very good physique in his late twenties.


Magnus is a dutiful person as he takes his job as a member of the CIA seriously and carries a atmosphere of not letting his personal thoughts get in the way of his duty.

However, despite this he is shown to have a compassionate side, as he wanted to make sure that the CIA wouldn't kill Meredith if she could be saved, with Rias Gremory praising him as a good human. Magnus says that his wife often tells him to care more about his family due to his job always getting in the middle of his family life.

Magnus is also shown to have a awkward side as he realized that during his duel with Ruval's servant, he accidentally destroyed Ruval's car while using his ability and begged Ruval not to tell his boss as promised to work hard to compensate the damage. Riser Phenex considers him a weird guy.


Not much is know about about Magnus' past except that he became a agent for the CIA and was able to rise up to the ranks to lead his own supernatural taskforce. At some point in the past, his Sacred Gear evolved into one of the 5 new Longinus.
