Complete crackfic idea but imagine some ninja (mostly jonin specialized but also some chunin) talking badly about Iruka. A minority really but a loud one who thinks him being in the Third good book is why he had all the future head of clans as his first class as a teacher and how he didn't deserves all those powerful connections. And whole fucking lot of bullshit about his attitude and his integrity.
It started from the 1st day he had his class and even some teachers were whispering about it.
(Well until Iruka made them stay one day with the hellions he had for a class and they learned to keep it shut.)
The thing is.
The thing is Konoha 9 is quite attached to Iruka.
It's well known that Naruto is the closest to him. Pretty shameless about it too. And Team 7 as a whole, even Sasuke softening up towards his old academy teacher.
Shikamaru show nothing but quiet respect, Choji remember snacks being passed down while being scolded about not eating in class and Hinata someone who taught her how to deal with panic attacks and a constantly opened ear and door in bad time.
A plethora of small things and small moments they all cherish.
Anyway ninja are talking shit about them and their favorite teacher and they are NOT about to take that shit laying down. (Naruto has to be held back from simply screaming and kicking asses).
Cue enrolling Hatake Kakashi, Sixth Hokage, professional troll and chaos enabler.
It's decided that some active shinobi shall take a turn as teacher for one day to "promote the importance of taking care of our youth in this time of peace" and "submit ideas to participate in making better the academy program and the future generation education".
The idea being heavily promoted by Konoha's miracle gen who generously proposed to give their time to the cause. Designated shinobis shall be assistant in the morning to the existing teacher body and have their own class made up of the Konoha 9 under henge as their younger selves in the afternoon.
The whole thing is obviously on a lucky basis with the Head Teacher Umino Iruka himself pulling name from a box.
Rumors may fly about Iruka afterwards but none ever devalued his skills as a teacher or the link he has with his former students.
