but it was very obvious from the ending that it was axed waaay before the author intended.

The author is the same as Hunter’s Guild: Red Hood, which had the same kind of rushed ending. There’s the saying “2 times is coincidence, 3 is a pattern”.

Regardless, I’m starting to wonder if the series aren’t getting axed early and instead the author just gets bored with an idea after a few dozen chapters and tries to wrap things up quick to move onto the next project. I don’t have proof, and it’s only been 2 instances so far, but it’s seeming like a potential explanation
