Don't take this seriously, I repeat this is just a plot bunny that I had.

"What?" Kazuma says as he hears the old man's words.
"It's just for the time being, so you're going to be in a team until you the people from your world figure out how to take you back or we figure out how to send you back." the Third Hokage says to Kauma.
'No I understand that part, but why can't I just work in a restaurant or pick up trash until then?" Kazuma says to the old man.
"Because you are an outsider, the Hidden Villages all share a few things one of them is that we don't like outsiders, you staying behind the walls will make you pass a bad time while you're here."
''So it's better if you go out and explore the world while you're in it." The Third says to Kazuma.
"Okay, so who is going to be watching me until I go home?" Kazuma asks the Third.
'I'll call you when we figure out your new team." the Third answers Kazuma, he doesn't say anything as Kazuma leaves his office, he knows that Kazuma is just going to go to the apartment that was given to him so he doesn't bother keeping an eye on him.
The Third can't help but smile, he hasn't heard the names Eris Aqua and Vanir in such a long time, and here in his old age, he finds someone transported to this world because of their actions.
Knowing them Kauma won't last very long in this world and if he does, then he is going to forget about everything he sees s, its better if the people he assigned to keep an eye on him aren't very capable.
While the potential is there, it will need a lot of work for it to show any results.
He wants to put another boy, but that could be a problem especially if he wants to make a weak team, infighting is already going to be a problem so why make it even worse?
He begins to look through the lowest students and he doesn't bother looking at Naruto's folder, the boy has enough power and potential to be one of the strongest ninjas in the village.
Hinata Hyuga, while she is the future head of the Hyuga clan she isn't cut out for the life of a ninja and while she will be able to get to the next step unless something drastic happens she won't ever make Jonin.
He picks up the next folder Sakura Haruno, the girl has excellent chakra control but other than that she doesn't have anything else, no inherited family ability, except for her second personality but that isn't very useful at this age.
The last folder belonged to Ino Yamanaka, at first he wanted to use Teten for this team, but unlike Tenten, Ino's ability leaves her completely open to an attack, and her physical abilities aren't very good.
If this four-man team can somehow keep itself together and learn to get stronger then maybe he will consider putting them in the teams that he wanted to put them in before Kazuma arrived.
For now, this throwaway team would serve to keep Hinata out of any real danger and help her get some confidence.
With a lot of luck, both Ino and Sakura will be able to learn and get stronger but if they can't then their abilities will stagnate and they won't be able to get very far.
As for Kazuma, he isn't worth anything, he doesn't have any chakra so he can't use any of the ninja skills, and since he isn't anything else but an Adventurer which is the lowest class he isn't worth much if anything at all.
Now they are going to need someone to teach them, but the person in question is someone who has more than enough time and won't care if the team is disbanded if it fails to do anything.
He can't help but smile. 'yes those two will do just fine he says to himself before ordering one of his guards to bring him Kotetsu Hagane and Izumo Kamizuki.
Normally a team would only have one teacher, but knowing both Kotetsu and Izumo if one was doing something then the other would be there, so why bother pretending that this would be any different?
