Mana Walker (マナ・ウォーカー, Mana Wōkā) is Allen's foster father, adopting him on Christmas Day. Over time, Allen formed a very strong bond with Mana. Eventually, Mana died for unknown reasons and Allen turned him into an Akuma. Mana sliced through Allen's left eye, cursing him and marking it with a pentacle. He was quickly destroyed by Allen's awakened anti-Akuma weapon. He was also a traveling clown. He is allegedly the older brother of the 14th Noah and taught Allen the "notes" on the 14th's music score. According to Cross, Mana began to lose his grip on reality by the time Allen was adopted. He is voiced by Fumihiko Tachiki.
