i mean how was it decided that Minato would teach a 5 year old? Minato had to have been only 16 or 17 at the time, if not younger (as i think Minato would have been in his 20s during Kakashi Gaiden). what would make someone that young want to take on a Genin that's pretty much a toddler? my personal opinion was that Jiraiya and Sakumo were old friends so maybe Jiraiya talked Minato into teaching his friend's son?
and then there's the whole, who are his two teammates at the time, since when they graduate they're put in teams of 3. was he Minato's only student until Obito and Rin graduated at 9?
yeah i'm a fan of Team Minato, so it's wishful thinking that Kishi would tell us more about the team, but whatever lol, that's why i said "wishlist," i'm not saying i expect so and so to happen, it's just what i wish to see.
