So here i get to know that Kisame fragments can be got only from the group shop for now. Hence if i want him, i can spend the group points.

In some cases, you can get the fragments from instance. For eg Sai

Unfortunately i didnt know about this before so I wasted all my ranked battle points on getting him. So i could have just done the instance and got the frags(or i would atleast know that i can get him for free later on if i havent completed the instance )

Hope this helps some . So yeah save those points. Cheers
