Wake up to build a new world

Kagashi Yutaka and his childhood friend Tatsuya Ikari were just living a normal life until one day a portal out of nowhere transported them to another world where monsters known as Noise threaten humanity. With just a mysterious suitcase and each other, will they be able to survive in the other world?

Inspired by Fenix1475 and Dekaconvoy. I see a lot of kamen rider x symphogear story and I wanted to take a crack at making my own version of it. Hope you all can enjoy it.
