Find Missing Treasure! Great Treasure Hunting Dog, Notarou.

Notarou has eaten ALL of the ricecakes. Upon a visit to a shrine to pray for good luck, Sano had encountered a chubby dog that looked sick. He took it to the Kamiya Dojo, where he found Megumi. The dog was treated, as it had drank too much water. Ricecakes were made by Megumi, and as always, Sano was starving. However, his new canine friend had the first dibs. The dog Sano had brought over had eaten all of the ricecakes, despite both Sano and Yahiko trying to pull him off. A name had to be thought up for such an animal. Notarou is what Sano suggested.

Aww, isn't that cute? In order to find Notarou's owner, Kenshin, Yahiko, and Sano began to post notices all over town. During the time spent at the Kamiya Dojo, Notarou had done his business freely in any room he pleased and even ate Kaoru's cooking. Sano was forced to bring home Notarou with him. Even that didn't work out too well; Notarou was a bit noisy. The following day, to see if his praying worked, Sano went off to the gambling halls, leaving Notarou at the dojo again. This time, Notarou not only tried to bury many precious items such as Kenshin's Sakabatou and Yahiko's shinai, but he was chased around, through the rooms and everywhere else, by Kaoru and Yahiko. By time Sano returned with nothing to show for the time spent gambling, he was forced to take Notarou back. However, Kaoru didn't want Notarou to step a foot in her household ever again. Without a choice, Sano dropped off the dog at Genzai's/Megumi's place.

"Yes, I'm looking for this lost little dog." Yahiko was persistent to have Kenshin teach him something, but since Notarou had also buried the laundry, Kenshin was forced to rewash quite a load. Unexpectedly, Police Chief Uramura greeted the two and asked for a moment with Kenshin. Kenshin put his washing on hold and listened to what the police chief had to say. Uramura spoke of a group known as the Kenwa, a gang of kenpo fighters who claim to be democratic. What the Kenwa want to do is use a key that government officials they had ambushed a few nights ago. The key is said to lead to a safe that contains evidence against "dirty" politicians, which the Kenwa want to use to blackmail them. However, the key had disappeared. When Uramura had seen the notice of Notarou, he came right over to the Kamiya Dojo. Notarou is the only creature that knows where the key went.

Too easy for Sano... Walking down a path, thinking about where Notarou's owner could possibly be, is Sano. Just up ahead of the path, to his surprise, is Notarou. Notarou runs up and greets his owner for the time being, but that's when a group of men wearing fox masks show up. They are the Kenwa, and they want Notarou to come with them. Sano tells Notarou to run off, which he does. With ease, Sanosuke the ex-gangster tears apart the kenpo fighters. By time Kenshin and Yahiko, who were looking for Sano, arrive on the scene with Notarou, Sano had already won.

What a nice feast. Back at the shrine where it all started is everyone. Kenshin asks Uramura for his glasses. The police chief hands his pair over, and Kenshin places it on the ground. With everyone else in hiding, Notarou sniffs the glasses and takes them away. Quickly, everyone follows. It's the same thing Notarou had done earlier; he was trying to bury items. In the hole where Notarou had dropped the glasses was also the key Uramura was searching for. With his thanks given to Kenshin, Uramura departs, but reminds Sano that Notarou's real owners want their dog back. Since they couldn't make it today, however, Sano is forced to hold the dog for one more night. Everyone heads back home to the Kamiya Dojo, happy that everything has been settled. Yet, Kaoru is mad because both Kenshin and Yahiko haven't done anything while she was gone. Sano runs away before he gets yelled at and stops over at Genzai's/Megumi's place not only to drop off Notarou, but to freeload on food as well.
