i dont think bee neds it it would do nothing against madara and tobi.... and no i think tsunade would have to be uchiha
Kishi's mind(Tim Jamison's analyses)Shouldnt being senju alone mean something
@2 I dont think bee likes the great sword design, and keeps it in good hands

1. can a senju like Tsunade evoke rinnegan if implanted with sharingan??
2. why isn't Bee using samehada in battle
