Review Detail of Cestarian in Assassin's Chronicle

The story starts out fairly interesting with a uniquely mature protagonist, finding his place in a new world and it's pretty interesting for a couple of chapters but after a certain event where the protagonist kills someone he shouldn't have and needs to go on the run, the story gradually becomes stale, the chapters become more long winded and I can't really get into anything because the story and characters seem to have become nearly completely aimless, I even skimmed like half of the chapters I've read and I never felt like I missed out a single thing. The protagonist has had completely no development since early on, and while the side characters do develop, they're very basic characters through and through, nothing special to see there. Everything always somehow just works out for the protagonist and there are plot holes as ridiculous as one chapter an arm of the protagonist get broken and the next it's like the author completely forgot... The worst thing about the translation is that htere are often pov changes that happen without any indication, we're literally talking about 1 paragraph being from mc's perspective and the next from another's, there's no transition at all most of the time. It's quite ridiculous.
