Crona is the gender ambiguous adoptive child of Medusa and another powerful meister. Throughout the story, Crona is used as Medusa's pawn to awaken Asura, the ultimate kishin. However, when Crona's attempts fail, Medusa is forced to use alternate methods. Unlike his anime counterpart, Crona's backstory and history with Medusa is never explored in this parody. He still exhibits his shy and reclusive attitude, but is merely used as a punching bag for Ragnarok and Medusa.
