[Oh hi Yondaime - TimeTravel AU]
It is him again, Tobirama, 28, sensei to 6 brats instead of 3 (Too many times he has to throw them in the forest and watches the animal chases those brat from afar. Because honestly, they can be quite a pain, even if Tobirama is really patient and loves those brat a lot, he still wants to throw them in damn koi ponds sometimes). But back to the current moment, thing is, Tobirama just convinced Hashirama to give him one week off from his duty (because he wants to spend his time in his beloved lab) and with a little trick here and there, Hashirama agrees take over the team for a week (maybe because Tobirama has been stressing a lot and Hashirama recognizes the sign), either way, he is free.
The Senju wastes no time, as soon as the deal is seal, Tobirama lefts and gets inside his lab, almost like a nerd. Honestly, this man just loves his lab too much, and knowledge, and creates new jutsu. You get the point. Tobirama, in a way, is a fucking nerd, but no one can blame him and not that he cares about what people think of him. He has never cares before, why must he cares now?
Tobirama has no idea how many hours have passed, he has been working nonstop for this jutsu, yes, he is trying to improve his Flying Thunder God, his space-time jutsu. It already fearsome, but it still isn't good enough, still hasn't complete yet, until now, or at least it is what Tobirama hopes. Too bad for him, Kami is bored and decides to give Tobirama a trip, with a loud bang, the Nidaime was gone. It happened so fast and Tobirama cursed himself, he was too excited and forget to have his clone test it first, but there is no turning back now. As the smoke slowly disappear, Tobirama finds himself in such familiar room.
He mumbles to himself, notices something seem off so he already has his hands on his weapon, only to realize he is in his normal robe instead of his armour, which means he doesn't have his weapon with him right now (why should he wears his armour when going inside his lab anyway?) Well shit.
