Mr. A (or rather, his host body) is the father of Reiko's child. Shinichi is forced to battle Mr. A when he attempts to hunt Shinichi down and kill him at school. Though Shinichi and Migi badly wound him, they are forced to flee before he can be completely destroyed. He is killed after their battle by Tamura Reiko for endangering her undercover lifestyle.

Birthday: September 30th (Libra) Commonly known as Break, he is a member of Pandora and a servant of the Rainsworth household. Break's appearance does not change from the ten year gap between Oz entering and leaving the Abyss. He has a legal contract with the Mad Hatter. Break is often seen with a doll on his shoulder, which he calls Emily. He adores sweets and cakes. From the outside, Break seems like a carefree character, never serious and always smiling. When needs be, however, Break shows his dangerous and evil side. Reim tells Oz that Break has not always been the way he is now. Before, after losing his eye, he was a bitter and angry person, never smiling. However, through the kindness of Shelly, Sharon's mother, he began to open up. He has sworn absolute loyalty to Shelly. Break has no left eye. He reveals that the Will of the Abyss took it from him and that the Cheshire has it. Break's true motive is to find the truth behind what happened 100 years ago. He hates Vincent with a passion. It was revealed by Rufus Barma in chapter 29 that his real name is Kevin Regnard. Break was originally a knight who served under the noble family Sinclair until they were mysteriously massacred for political reasons. His lord was killed during the incident while Kevin and the daughter of the lord were out. Kevin blamed himself for his carelessness, and became an illegal contractor to try to change the past. When his clock made a full revolution, he was pulled into Abyss where he met the Intention of the Abyss and a young Vincent. The Intention of the Abyss once changed the past for Break. In return, Break was asked to fulfilled her wish, which is still unknown. Break then was sent to the Rainsworth house over 30 years later. However, the changed past wasn't really what Break wanted. The Sinclair family was still murdered. According to Cheryl, the oldest daughter of the house was assassinated, which led the younger daughter to become an illegal contractor and got sent to Abyss after her Chain murdered the entire family. The political massacre did not happen and Kevin's lord lived for 4 years longer, but instead, the little girl who originally survived the incident died. Break blames himself for that. For one moment he also blamed the Intention of the Abyss, but he realizes that he was the one who asked for the past to be changed, and in reality, he really just wanted to erase his own guilt.
