Hello!

Naruto [Sage of Six Paths] isn't available yet from the mother source of the game which is the CN version. That being said, his Breakthroughs will be not available yet in the near future. But rest assured, when there's such an update like that and we're about to release it here in EN, we will inform you all through our New Events Threads so for now, let's be patient and have fun with what we have. Thank you.
