Madou Necklace Silva (魔導具シルヴァ, Madōgu Shiruva?) is the Madou Necklace of Zero. She belonged to the former Silver Fang (Rei's father) and serves the current one. She takes the form of a Madou necklace of a woman wearing a mask. Silva is voiced by Ai Orikasa (折笠 愛 Orikasa Ai?).
It was Silva that identified the killer of Zero's family was related to another Makai Knight.
In Garo Special: Beast of the Midnight Sun, Silva is no longer a necklace. Her head has been pinned to Rei's glove. Towards the end of Beast of the White Knight she suggested Rei to take Akatsuki as his student, but Rei said Silva's company is enough.
Silva is affectionate towards Rei and often gets jealous or possessive when other women interact with him.
It's unclear of Silva's true potential since Zero never once used his blades or techniques with Silva as Kouga does with Zaruba. For now she's merely an advisor and Horror detector.
