I need some help finding a manga

[Uk2897]

MC started in his normal world. He was in the army or some faction for safeguarding. He was about to go meet up with a female friend or maybe as their meetup was over a distortion occurred. He was transported a parallel type version of his world.
Saved a girl sealed somewhere and when to an underground refugee type city. Where he met his old comrades but none of them knew him. Kinda lead by a female character who was a friend of his.
He gained their trust as they were defending from "demon attacks" ig.
They then went to the demons (female demon. hot af) base to fight them. And defeated them. The girl MC initally saved was also a factor in the battle.
MC uses a sword.
In the scene where he saves the girl some robotic android type being comes to eliminate them

this could even be mixing 2 mangas into one.. So... I apologise

I've had that happen before.

I'm pretty sure I watched the anime for it a while back, so your description made it pretty easy to remember what series it was.
