Something that got me wondering, We saw how many people were after Hashirama Senju's DNA and all but why not Tobirama's or even Tsunade ? Those two are senju as well plus strong in their own right and i surely doubt it's soley to acquire the wood release kekkei genkai so what are your thoughts on this subject ?
WELL
1. Hashirama is unique, Tobirama, hahirama's blood brother doesn't have the ability like hashi to solo bijuu's on his will.
2. Tsunade is a cross of Uzumaki, Senju and many other unknown blood so her dna is poisonous to health, some thing mudbloods (impure-blood) that is why guys in NV are not interested in her DNA..
