Does it ever reveal that?
please refer me to a chapter/page number or episode for proof if you do know
thanks
Maybe he stole it from madara
wtf they don't have to show you every thing , all they need is to tell you that his jutsu requires dna
the jutsu needs dna, end of story. you only bother yourself by thinking this hard
sigh.. i suppose U_U
does it really matter? we know he got it while he was still part of konoha (yamato is proof of that)
