Mrs. Christel (クリステルさん, Kurisuteru-san) is a character in the video game No More Heroes. She is the mother of Sylvia Christel. After ranking second in the United Assassins Association, Travis Touchdown becomes agitated by the disappearance of Sylvia and tries contacting her via the UAA's hotline. An older woman answers the phone, shortly after which she reveals herself to be Sylvia's mother. When Touchdown asks about the Association, Mrs. Christel sighs in disappointment, and shocks Touchdown with the revelation that the United Assassins Association does not exist. She goes on to tell him that Sylvia is a professional con artist, and that Touchdown is not the first assassin whom she has fooled. Despite the ruse, Mrs. Christel goads Touchdown into facing the first ranked assassin, in order to finish what he has been thrust into.
When Touchdown returns to Santa Destroy three years later, Sylvia encourages him to rejoin the UAA rankings, even inviting him to the UAA office, cementing that the UAA rankings clearly exist. Mrs. Christel and Sylvia share the same voice actress, Paula Tiso, which may suggest Mrs. Christel was in fact fabricated by Sylvia following her desertion after congratulating Touchdown in Speed City. Another possible explanation is that the events of No More Heroes 2: Desperate Struggle, in which Touchdown returns to the UAA, are a complete retcon of Mrs. Christel's dialogue in the first game. This is an equal possibility in that a sequel was not originally envisioned for No More Heroes, and so as the story was originally written, Touchdown's Ranking Battles may have truly been nothing more than a setup rather than a climb to number one on any official leaderboard. Mrs. Christel is not mentioned or alluded to elsewhere in the series.
