Long Time No See: Jiraiya Returns!

is episode 53 of the original Naruto anime.

Synopsis
Naruto tries to wake up Ebisu using One Thousand Years of Death, but nothing happenes. Naruto then asks him who he is, and Jiraiya introduces himself as the Frog Hermit, though Naruto starts calling Jiraiya 'Pervy Sage'. He said that he was a writer of novels, and he pulls out his newest book, 'Icha Icha Paradise', Naruto concluding that his data gathering was "peeking". Naruto gets angry that Jiraiya "interrupted his training", and said that he should be responsible for his training because Ebisu was incapacitated. Jiraiya refused and left. Naruto was impressed and thought that he was cool, and he left Ebisu behind to follow Jiraiya.

He searched for Jiraiya and found him in a sweets shop, after a girl had just slapped him. Naruto then confronted Jiraiya about his responsibility for his training, and started calling him a pervert in front of the general populance. Finally, Jiraiya picked him up and put him in a big jar; putting a large rock on top of the lid so that Naruto couldn't escape.

Jiraiya is then seen sitting in the forest outside the town, looking at the clouds, and imagining them as nude girls. Suddenly, Naruto attacks him with some shuriken, and Jiraiya ducks behind a log, appearing to use his Body Replacement Technique to escape, and Naruto runs off to search for him. But Jiraiya had actually used the Transformation Technique, and turns back to himself after Naruto is gone, bragging that he would have to train a thousand years to beat him. Naruto then appears behind him, commenting that it actually wasn't that hard. (The earlier version of him had been a shadow clone) Finally Jiraiya says that he will supervise Naruto's training if he is able to being him a nice 'mellon'. Naruto agrees and runs off, Jiraiya sees two ladies, and runs after them.

He talks with the ladies, then Naruto arrived, with a matured watermelon. It seems that Naruto misunderstood the request. Jiraiya let Naruto eat the watermelon, unfortunately, the girls left. Naruto and Jiraiya had a short fight, with Jiraiya saying he needs a babe, so Naruto transformed using his Sexy Technique. Jiraiya and the hidden Ebisu had a nosebleed, but Ebisu's was similar to the Third Hokage's. Finally, Jiraiya was convinced. He told him to remain in that form so he will supervise his training. Naruto get disappointed, so he return to his original form. Jiraiya then openly admitted that he was a super pervert.

Jiraiya admitted that he was kidding, that he will really supervise Naruto's training. Naruto resumes his water-walking practice. But he can't still stand in the water. Jiraiya laughs at him. Then, he saw the Four Symbols Seal at Naruto. He realised that this was done by the Fourth Hokage to protect Naruto. He also saw the Five Elements Seal, thinking this was done by Orochimaru, he removed the seal using the Five Elements Unseal. After removing the seal, he asks Naruto to walk again in the water. At last, he can walk now in the water. Jiraiya thought that this was the time to teach him how to use the Nine-Tails chakra. But before that, he told Naruto that he has two types of chakra: red and blue chakra. Jiraiya then says that they must stop the training, and they must head to the hot springs. After they bath, Naruto sleep, then Ebisu arrived, Jiraiya then apologize that he stole his student, then he said that the Hokage was searching for him. Then Ebisu said that he was one of the Sannin, so he can stop Orochimaru.
