I managed to get Killer Bee twice (both the "full ninja"). Usually when you get a copy of a 3* ninja you get 20 fragments. On the copy I got 2 fragments, does that mean since it is an time-limited event, you get only a tiny amount?
You can technically pull his frags during this. Doesn't actually mean you pulled him as a character. I've pulled for Kazekage Gaara. Got everybody and managed to get an extra 8 Bee fragments, You probably were mistaken when you pulled the 2 fragments.
