Yeah so the people in naruto all learned their jutsu from their sensei. Kakashi and sasuke (sasuke knows chidori), jiraiya and naruto (rasengan), tsunade and saukra (medical nin). So like, depending on your alignment, stats, and DKs you could choose your sensai which could teach you a few of their jutsu in an event. So for this i'm gonna use Sasuke as the sensei and pretend chidori isn't in rai ninjutsu. This would be an event kinda of like the curse seal 2 event except you only have to pay once. So lets say i beat the training and paid the gems. I learn Chidori. BUT their are many types of chidori. Sasuke's types. Chidori Nagashi would be the next level for more gems. Also you would keep these as long as you keep that sensei. EX: IF i have sasuke i keep those chidori moves. I cant use kakashi's double raikiri only sasuke's.
