The Devil Bringer is the "weapon" that takes the form of Nero's right arm. Its origins remain a mystery but it bestows upon Nero incredible power, including the ability to bend space and time to pull himself across distances instantly and pull enemies to Nero. Nero states, after receiving the Yamato, that "From that day forth, [his] arm changed and a voice echoed 'Power. Give me more power.'" It seems to also give him incredible strength, as he is able to parry the sword strike of Berial, who is almost five times Nero's height, with his Red Queen. The story seems to focus some attention on the Devil Bringer, its powers, and its origins. It also seems to disturb Kyrie, the main female lead in DMC4, that Nero possesses the Devil Bringer, possibly because it is obviously of demonic origin, but after saving her from Sanctus, she comes to understand Nero and accept his arm. The arm allows Nero to absorb certain items, such as the Yamato, and gain their abilities. It is by doing this that Nero attains his Devil Trigger.
