The Daimaō orders Sorges to defeat Chacha again, and Sorges asks why he is so interested in Chacha, but gets no answer. Meanwhile, Chacha and her classmates are graduating, but the Nezumi Kid has announced his intention to steal the Graduation Stamp, thereby preventing the students from graduating. It turns out that Nezumi Kid attended the school the same year as Seravy and Dorothy, and left the school after losing a disguise contest to Seravy. Chacha and her friends, along with Mr. Rascal and the principal, are guarding the stampe when Seravy stops by disguised as a "just passing by" master detective (and assistant, played by Elizabeth). Later, he drops by again only to have a second "just passing by" detective come in, and both look the same. The students are able to determine the fake (Nezumi Kid) as he does not have an assistant, but the lights get turned off. After they come back on, there are two Mr. Rascals and Seravy is gone. The Nezumi Kid is able to trick the kids into believing he is the real Mr. Rascal, and escape with the stamp as Chacha and her friends realize their mistake and begin chasing him. While attempting to grab the stamp, Orin gets trapped in a bag designed to tighten as she struggles more. Seravy (still disguised as the detective) then stops Nezumi Kid from running and tells Chacha, Shiine, and Riiya to take care of Nezumi Kid. Nezumi Kid tosses the stamp up into the air where Sorges is waiting in a helicopter, but Shiine summons a cannon and shoots it down. Nezumi Kid has other ideas and sends a duplicating robot after them which duplicates whenever it is attacked. The more they try to destroy the robots, the more those are created. Chacha summons a giant cat statue and smashes them all, but they merge into a giant rat robot which then attacks. Chacha transforms into the Magical Princess, being only briefly interrupted by Marin, and defeats the robot. However, the stamp has been taken away by Sorges. His damaged helicopter crashes into the mountains and the episode ends. (Source: Wikipedia)
