You still don't understand, do you. The burden of proof is on you. All of the nonsense you pull does not prove Minato used Hirashin to reach the battlefield,. A Hokage who can't differentiate between space/time and Shunshin, even though he uses space/time himself, I've never heard of something like this. Tobirama could've at least suspected it was space/time that Minato used if he saw him teleporting, and not compliment his Shunshin, which is an advanced form of foot speed. You need to get your stuff together. Tobirama being a fellow space/time user knew Minato used Shunshin, it's not like the speed of Shunshin can be compared to a space/time technique like Hirashin. And I'm still awaiting your proof regarding Minato's hidden marking in the battlefield, that no one noticed except you.Still not getting it bro
Hiraishin is the name of his flying thunder god, its not what everybody (including you) calls teleportation. Its minato's own personal name for his own personal jutsu. Now please explain to me how tobirama would know what minato's jutsu is called (I know he has a FTG slash but that still doesnt prove that tobirama knew what minato calls his own jutsu).
As I said you would be seriously ignorant to think tobirama knew that minato's teleportation was called Hiraishin (Flying thunder god), because he has no prior knowledge on what minato names his jutsus. So until you can prove that tobi knows what hiraishin is then you cant win this argument.
Btw that top part of your argument is irrelevant because you simply cant prove that tobirama knows what minato calls his "hiraishin".
And way to avoid a large portion of my post again.
