As everyone gets ready for Christmas, the Jūden-chan have their work cut out for them. Reka and Kuran visit Sento and warn him about Hōden-chan (discharger girls), who steal people's positive energy. As Plug wonders about if she should get Sento a present, Arresta already has one in mind. One of the Hōden-chan, Rona Elmo, targets two people who pick a flower she liked. After apprehending an electricity thief, Reka and Kuran eventually find Rona, but are badly defeated. Sento discovers them and is left unconscious. Incidentally, the entertainment news reporter on TV who identified herself as "Hirano", is the voice actress for Rona as well.
