Hello everyone!

I need your help. I have been racking my brain for a few days now trying to remember this one manga I read a few years ago. I've researched on my own but I just couldn't find it. I hope someone here can help me out.

So, basically, the manga was about this girl and her partner who was an anthropomorphic aircraft of some sort (I think he was a fighter jet). Some special vehicles could become ensouled beings but they can be dangerous once they do so there are these girls who become their partners who they form a contract with to sort of tame/control them (this is the situation of our MC and her partner). These ensouled vehicles have a humanoid form (but can transform into their vehicle form when needed) and are powerful. I remember a scene where a military vehicle of some sort (dunno if it was a ship or an aircraft) appeared and everyone was on high alert because it was ensouled and went berserk. MC's partner fought it.

The story is set on this "world above Earth". Vehicles would float up to their world/city. I can remember a scene where there were lots of various vehicles being tied down by ropes. It's like... Their world is where vehicles go to when they "die", I think.

And also, once an ensouled vehicle forms a bond with someone, that someone gives them energy by... you-know-what (at least that's the case with MC and her partner). Plus, there's also a mystery surrounding their world, and the vehicles, and the girls who have the ability to form a bond with them.

It was a very interesting story. I really want to read it again because it might be completed by now. I would greatly appreciate your help!😁
