Chacha receives an invitation to a class reunion, and everyone is excited to go. The Daimaō is not pleased that Chacha has found all three of the legendary weapons. Harpy volunteers to destroy Chacha due to her hatred of the former king (he banished her after she tried to seduce him into making her Queen). Seravy and Dorothy are worried about the three young adventurers as the enemies they've been fighting have become stronger and stronger. Dorothy suggests that they can always "pass by" and help them as in the past, but Seravy says that only those with royal blood can defeat the Daimaō. Dorothy has an idea, though. She suggests being disguised as monsters and attacking the trio in order to analyze their weaknesses, then helping them out with those later. Shiine overhears them talking and tells Riiya and Chacha about it. Shortly afterward, Marin, Yakko, Mr. Rascal, Mr. Barabaraman, and the principal arrive, followed by all of their former classmates, so the class reunion begins. Chacha goes into the restroom to wash her hands, and Harpy starts to attack, but is thrown off guard when Chacha thinks she is Seravy in disguise. Yakko arrives, and accidentally blasts her out of the building by using the wrong potion. Harpy charges back in and is mistaken as a former student by Mr. Barabaraman, then roped into being the target for the principal's knife throwing show. Seravy and Dorothy show up in the monster disguises at that point and Harpy begins attacking. Chacha transforms and summons the Phoenix Sword, attacking Harpy before Seravy can stop her. The Wing Kris Burning Flash only causes Harpy to grow as she absorbs the magical power. She then blasts the Magical Princess and seizes her. Seravy wants to assist, but Dorothy stops him. Yako and Marin try to help, but their attacks are shrugged off, as are attempts by the principal, Orin, Mr. Barabaraman, and Mr. Rascal. Harpy tells Chacha that after she kills her, she will smash the statue of her parents, thus destroying the royal family and allow demons to rule the world. Chacha is able to summon the Bird Shield and reflect Harpy's own attack back onto her, thus destroying her. After the battle, Seravy tells Chacha it is time to go to the castle. (Source: Wikipedia)
