Looking for a manga as well.
I dont remember a lot about it but I would be thrilled if anyone can find it. Heres what I remember, people have power, they gather together close to some sort of gate and train there. At some point member for the other dimension attack them. Thats pretty much it. I Know its not much. It went on a break and I lost track of it.
