It's really no surprise why this got axed. After resolving its core conflict in the first 3 chapters, there was nothing really unique or interesting left for the story to show. I'm honestly surprised it even lasted this long.
I read everything
all I can say, this is why im grateful manga doesnt adapt wn/ln 100%, this truly has become so convoluted beyond necessary, truly 8th grade , Grade A Chunibyou syndrome there, like Shield Hero, yeesh
