Jiraiya's quest starts automatically after Day 100.
Before progressing through the quest, make sure you have:
Go to the River Bank.
You will find an old book near the river. After picking it up, Jiraiya appears as a ghost and explains that his chakra is connected to the book.
After a short conversation, you decide to continue somewhere else.
Open the book with Jiraiya.
It turns out to be an unfinished erotic photo album. Jiraiya cannot move on until the album is completed, so he asks you to help him finish it.
During the conversation, you discuss possible models:
After that, you decide to visit the hot springs. Before going there, you realize that you need a camera.
Go to Tenten's store and buy a camera.
After that, continue to the hot springs.
Go to the hot springs.
You will find Hinata and Sakura there.
Approach Hinata when she is alone.
You will take a photo of her at the hot springs.
After that, approach Sakura.
You will take another photo for Jiraiya's album.
Go to the Training Ground and talk to Ino.
If Ino's Lust is less than 10, she will refuse.
If Ino's Lust is 10 or higher, she agrees to help.
After taking several photos, the scene continues and you spend the night with Ino.
The next day, you wake up at home and talk to Jiraiya.
Jiraiya says that the next target should be Karin, but getting her photo will be more difficult.
You decide to ask someone for help.
Go to Orochimaru's lab.
Jiraiya does not like this idea, but Orochimaru can see him because he was the one who threw the album into the river.
After some arguing, Orochimaru agrees to help. He suggests using a fake letter from Sasuke to convince Karin.
Come back the next day to collect the letter.
Return to Orochimaru's lab the next day.
Orochimaru gives you the fake letter from Sasuke. He also says that Karin went to the forest to gather herbs.
Go to the forest to find Karin.
Find Karin in the forest.
You tell her that Sasuke asked for a photo of her. After reading the fake letter, Karin agrees to pose.
Follow the scene until you take the photo.
Return to Orochimaru.
You need to pay him to develop the photos.
Photo development costs 250 Ryo in total.
If you do not have enough money, Orochimaru will refuse to continue. Return once you have 250 Ryo.
After paying Orochimaru, wait until the next day.
Then return to Orochimaru's lab to collect the photos.
Go to Orochimaru's lab.
Orochimaru is not there, but Karin gives you the envelope with the developed photos.
After leaving the lab, you meet Naruto. Jiraiya asks you to deliver his message to Naruto.
After that, return home.
You place the photos into the album. Jiraiya thanks you, his unfinished business is complete, and he disappears.
