If you look at the last panel the momment Hachibi is preparing we already see Tobi getting away from the area, it seems he cant afford havint go use Izanagi during this fight.
I didn't think about that at all. So maybe he can't use his stn due to controlling the paths.well if you think about this way he is controlling the path's so he must focus on them too maybe if he teleports he would lose his chakra signature to the path since his chakra erases once he teleports have you ever thought about that.
if he did it quick like intagible than it's different it's not like he teleported
Why would bother fighting in the first place when his pawns are fighting for him?If you look at the last panel the momment Hachibi is preparing we already see Tobi getting away from the area, it seems he cant afford havint go use Izanagi during this fight.
