Mr. Rascal and the Principal are back at the school while Chacha and friends continue searching for the Graduation Stamp. Sorges is consulting with his subordinate, Oroshi, to find out if it had seen where the stamp went. Chacha and her friends are traveling through a wasteland and are getting very thirsty. Chacha summons a giant can of juice, but not even Riiya can open it. Marin appears and summons water, but it is salt water and causes them to become more thirsty. Chacha's magical ring and amulet begin glowing and the larger gems detaches itself and begins leading them across the wilderness where they find an apparently deserted village. The village is not actually deserted, and the villagers welcome them with a feast, but it is interrupted with one of the village children saying he is hungry. The villagers then tell Chacha and friends about Oroshi, an eight-headed hydra, which has damaged their fields and the village, and the only way to appease the hydra is to offer a maiden as a sacrifice. The villagers state they want one of the two girls in the group (Marin or Chacha) as that sacrifice. The two girls aren't very supportive of the idea, but the villagers beg them and bring in the sacrificial bier which happens to have the Graduation Stamp used as a decoration. Chacha and friends decide to go through with it and defeat Oroshi so they can take the stamp and graduate. Chacha is dressed as the maiden sacrifice, and the villagers explain they need two sacrifices and Marin will be the second. The bier is taken to the sacrificial spot and Oroshi appears with Sorges riding one of the heads. Chacha and Marin cause Oroshi to get drunk, but Sorges sobers the hydra. As the hydra grabs Chacha, Marin grabs the stamp and runs away with it and finds Riiya and Shiine on their way to rescue Chacha. After a brief fight, Chacha transforms and defeats Oroshi. Back at the school, everyone is happy the stamp is back. However, Chacha and friends were not aware there was still a week of studying for the final exam before they graduated. (Source: Wikipedia)
