Shelly Mjolnir/Stein (ã‚·ã‚§ãƒªãƒ¼ ãƒŸãƒ§ãƒ«ãƒ‹ãƒ«/ã‚·ãƒ¥ã‚¿ã‚¤ãƒ³, SherÄ« Myoruniru/Shutain) is the daughter of Marie and Stein, the result of a drunken one-night-stand shortly before Marie left for Oceania. Shelly grew up in Oceania with her mother, never meeting her father, and Stein never being informed that the girl existed. She moved to Death City with her mother when Lord Death assigned her as Stein's temporary weapon, but it was still a while before Marie enrolled her to Shibusen and finally told Stein about her. Shelly is a Meister, and becomes Chris' partner after Ava's death. Shelly often tags along behind Stein like a puppy, eager to get to know the father she grew up without. Name Relevance:Shelly's name is a continuation of the pun of Stein and Marie's name's, playing on the novel Frankenstein by Mary Shelley (Franken Stein, Marie, and Shelly).
