I always wonder how the mechanic of xxxx render modern weaponary useless. In this kind manga. This time, they even use nuke and it was ineffective. Like how? how it works? wether it was magic or kinetic. At the end of the day they are all just energy. Newton 3rd law should still affect everything.
The manga i alaready forgot the title of explain this by the world being on different plane of existance, making them normally unable to interfere and they can attack each other because they can manifest in each other's dimension.
I wonder if there's going to be explanation about it. Or it would be just explained by it was magic.
