This idea is similar to previous ideas I had where the character has an aircraft armor like they do in Azur lane but thanks for reading other fanfics recently it popped in my head this idea our main character probably should be a girl because I just feel like it should be with anything that has to do with azur lane so our main character if we do like an isekai story is a really big Ace Combat fan let's say after doing a Ace Combat series marathon where she plays all the games one after the other to 100% buying all the airplanes unlocking the secret airplanes as well as all the equipment you can buy I don't know something happens and she ends up in Azur lane or a new favorite story world I've been seeing is the story Worm but obviously I'm not writing this story so you can put her into any world you want to. The main premise is that she has a system that allows her to interact like how you do during the briefing in the Ace Combat game where you select your airplane as well as your equipment but she also has access to the other air vehicles like the aircraft Command Center in Ace Combat 6 or the aircraft drone carrier in Ace Combat 7 so yeah any sort of aircraft that you either use or fight in the Ace Combat series the reason for this idea is to kind of give her an edge since planes are pretty brittle when you think about it and most like Multiverse worlds one good shot or even a punch could possibly take her out like in any of these anime worlds or superhero worlds so to kind of give her an edge besides being able to change her aircraft she can change on the Fly but it has a cool down so the situation is if her airplane armor is damaged enough where she can no longer fly or she is crashing she can switch to one of the other aircraft she has purchased also obviously certain aircraft can equip different equipment for example the two big planes that I mentioned earlier the Ace Combat 6 one would let her act like the aircraft carrier girls in Azur lane while the other one the Ace Combat 7 would give her a squadron of UAV drones switching between aircraft will just reset her armor health as well as change how fast or how armored she is, she will not restore ammunition she has a set amount of ammunition for any and all Weaponry that she has purchased so she only has a certain amount of normal missiles and a certain number of the secondary weapons but she can also switch these just like her airplane and just like how different airplanes have a different machine gun not all of them have like a minigun on on them like the warthog so I guess you would have two different sets of machine gun ammo for both styles of guns. And the reason I say Multiverse is that I took an idea from another fanfic the main character is in our world the normal world I guess or at least it seems like it and his Ace Combat system which pretty much encompasses anything that could have any word with Ace piloting like Gundams or anything you actually pilot he can select missions which will transport him to a world and he completes the mission then teleports back home or he can free roam in that world where he can roam around and get lucky and find New Missions so it's this idea that this story could use or you could have the main character stay in one world for a decent amount of time she solves the story or she you get the idea completes the story and then you can have her wish to explore new world and she chooses to go to it pretty much up to whoever decides to write this story if someone does.
