Kotone Amano

Kotone is Nene's younger sister. In the manga, Nene is helping DarkKnightmon because he promises to help Nene free Kotone, who is in a coma and sealed within a crystal. She is considered a General, and DarkKnightmon plans to use the Xros Codes of Kotone, Nene, and either Kiriha or Taiki to create the Darkness Loader. However, Nene sacrifices herself to take Kotone's place as DarkKnightmon's puppet General, while Xros Heart and Blue Flare rescue Kotone, with her becoming one of Xros Heart's Generals.
