Pretty disappointing as a first chapter. Nothing really happened. This would have been a fine chapter down the line (potentially interesting if it was our first POV change and the other chapters were from the mc’s perspective), but as a first, it’s really just bad. It does nothing to introduce me to the characters or start or kickstart the premise or even make me remotely interested. There’s nothing funny happening. So little happens, I don’t see why the author couldn’t place this chapter literally anywhere in the order. There’s very little to indicate when this is happening and nothing is established. Which again, is fine for pretty much any, but the first chapter (especially going off of the premise the manga is going for based off the description). There is a reason why the first chapter is sometimes much longer than the rest, and I didn’t need a 60 page opener. 15 is fine, if done not like this. Just give me some immediate introduction to the story and characters.
