Have a saved game from Naruto: Narutimate Hero 2 on your memory card to when starting a new game. A confirmation message will appear on the blank screen just before the loading screen and the main menu appears, stating that you have earned 607 Naruto Cards and 50,000 Ryou.
Just before you jump to RPG mode, play Naruto Eiyuuden (Story mode) first. After completing this mode, you can earn at least 50,000 to 60,000 Ryou.
While playing RPG mode and you are inside the Central Area of the Konoha Village, do the following. Go to the room where Iruka-Sensei is located (the house in front of Ichiraku Ramen) and talk to him. Select the second option, then the second option again. Go out and you will find scrolls on top of Ichiraku Ramen. Repeat this if desired. Collect a total of 999 scrolls, then convert them to 99,900 Ryou at the Scroll Shop.
If you want to do some things while collecting Ryou, grab your map and choose the dot on the southwest. Inside, enter the first door. Inside are some slot machines. Try playing one of those to earn more Ryou.
