It feels like someone cut out all the pages of a book took copies and then dropped them on the floor. By picking them up a few pages shifted positions and the copies got mixed in. the only way I could describe the entire backtracking. that or the author has amnesia and forgets where he was in the story at the start of every new chapter.
Ch 16 arrives at school. Chapter 17 jumps back to halfway chapter 16 before he was sent to school without warning.
It's hard to read to say the least. It jumps between time, art style, references, puns, names so much that it's all a blur.
The plot seems decent, execution blows.
