Let's get it going.
I'll start, i have three good ideas:
first one is called Loli FireFighters
So basically, 5 middle-school girls (the bland mc who has a tragic backstory, involving fire, the rich girl, the otaku, the smart girl and the sporty girl) join a training program to become firemen. They all pass and find an old fire department. They fix it up, get some firetrucks and put out a really dangerous fire. Then they decide to train, to become better at their job. But instead of training, they eat, have sleepovers, go to festival, the pool and the beach. Then they find out that some mean girls from their school also formed a fire fighting team. Those mean girls manage to put out a fire that the main team could not handle because they did not train enough and thanks to their incompetence, 8 people died. The girls are really bummed out by this and get depressed. But then one little girl that they saved comes to them, thanks them for saving her and tells them, not to give up. Then a really huge fire brakes out and even the mean girls ant handle it. But at the last minute, the main characters decide to help the mean girls. They put their differences aside and put out the fire. Then they all become friends and continue to keep the city safe.
The anime will have 12 episodes, one theatrical film and alot of ova's, chibi specials and picture dramas.
Also this anime will feature fire proximity suit's that have miniskirts, instead of pants. And also, alot of panty shots, when the girls are sliding down the fireman's pole.
