Episode Title:
Curse of the Power Stone.
Episode Description:
Masato informs Tsubasa that the power stone, now corrupted, contains enough dark energy to curse someone, and encourages him to curse Rinne with the help of a demon book picked up from Hell. He instructs Tsubasa to place his hand on the book and simply wish before departing. Tsubasa refuses and dumps the book then and there. However, after watching Sakura give more cookies to Rinne, he becomes jealous and finds himself cursing Rinne to be struck by lightning, as well as the demon book being returned to him. Frightened, Tsubasa dumps it away only for it to be returned to him by Rokumon, who thought it was his notes, just at that same moment when he was blaming Rinne for "taking advantage of being poor so that he could mooch of Sakura". At that moment, crows fly into his house and steal all the cookies given by Sakura. Even more frightened and panicked, Tsubasa also realises that the power stone becomes darker each time he curses and decides to gift Rinne a good luck charm secretly that can ward off curses, only to find that Rinne gave it to Sakura instead and curses him, causing rain to leak through the roof and coincidentally on Rinne, wetting his food. Tsubasa tries to burn the book but it is returned again just as he finished setting a trap for Masato, who wants to receive Tsubasa's corrupted soul to Hell. The trap transports Masato, but also Rinne who had deduced this was all his doing. Tsubasa accidentally curses Rinne again and decides that the ultimate punishment is for him to curse himself to die and go to Hell, which clears the power stone halfway because it reflects its owner's soul. He also receives a bounce-back curse and successfully clears the power stone. However, it darkens a little again when he get jealous of Rinne later.
