In Jewelpet Kira Deco, he is a member of Decoranain and the show's most active antagonist. He answers directly to the Dark General, a man he considers his father. On his mission to get the Deco Stones and corrupt them with darkness, he enlists the help of Opal and Io, who hate Ruby and her friends. Although he loves to boast that darkness is his only mistress, his continuous failures and humiliations eventually catch up to him.

In Jewelpet Happiness, he forms a Magic Gem.

He's a background character in the other seasons.




  • Coal's jewel motif is the coal, a type of fossil fuel.
  • Coal's appearance and personality is a tribute to Baku, a character from Studio Comet's previous Sanrio series Onegai My Melody.
