Karin is having a costume party and invited everyone, from Ikki, Erika, and Metabee (who are real glad to be invited) to Samantha and the rest of the Screws (who were surprised to get an invite). Koji decides to confess his love to Karin at her party. Just as he's about to confess his love, the Rubber Robo Gang crashes the party and with all the confusion, Kouji confesses his love to Samatha, by accident. But she thinks he's really telling the truth.
