Nanashi (ナナシ, Nanashi, "Nanashi" meaning nameless) is a character and major protagonist in the manga and anime series MÄR: Marchen Awakens Romance by Nobuyuki Anzai and the sequel series, MÄR Omega, by Kōichirō Hoshino. He is a member of Team MÄR and the leader of Luberia, a powerful thieves guild.
Nanashi is one of the more mysterious characters in MAR. Nobody knows his past for sure but we have our suspicions. We suspect that he is from Nobuyuki Anzai's previous work Flame of Recca. If you have read or watched it before, you might remember that somewhere near the end, Joker was sucked in the black hole and never seen again. We suspect he is Nanashi. Think about it, when he was found in MAR heaven with a wound in his gut, he was wearing the same clothes as Joker was when he was sucked in the blck hole minus the hat. He is also wearing the same bracelet and hasn't ever has it taken off. He also has a personality similiar to Joker. I just hope that Nobuyuki Anzai or his helpers come out with it and tells us this is true.
