So I think chuuni is a kind of diminutive of the word !Chūnibyō is a colloquial Japanese term typically used to describe early teens who have delusions of grandeur, who so desperately want to stand out that they have convinced themselves they have hidden knowledge or secret powers.
I run into something like that sometimes. It happens when they upload the entire chapter as one image, so it becomes too big to render properly or something. Downscaling or right click -> save image is the work-around I use.Why do I randomly get chapters that are 80% just a blank image file? It is never consistent with what story or scanlator it is, but if it happens that chapter is permanently broken for me. Does anyone ever run into this?
