Welcome to Saga~ A lot of what you need to know you can find in the guide to getting started, which can be found in the banner, or, if you're on mobile, here: http://www.narutosaga.com/t17853-the-guide-to-naruto-saga
If, after reading through that a bit you have any specific questions, don't hesitate to ask either via here, the chatbox, or via PM~ Look forward to seeing you around, and happy ninja'ing!
Welcome to the game. There've been a lot of new folks lately. Feel free to hit us up in the chat box. I know I'm not the most reliable for information but I'm happy to help with the questions I can answer!
