Mito honestly because I see no reason for him to wait and let hashirama take his woman , we are talking about yujro hanma after all đđ
and he has been too nice in his conversations this whole story
Depends if you want to stay somewhat canon or not. Without mito you lose tsunade and her brother as well as her being the nine tails vessel, since i assume yujiro wouldnât want the nine tails trapped so he could fight it.
