Well this is going to be a review for this fanfiction. Do keep in mind, this was only done at the point where I read up to the latest chapter, so yeah.
For writing quality, there are quite the number of grammatical errors within the work, whether it be completely different words used or incorrect spelling, it can be remedied, I understand that much.
The story development, it's understandable but this is coming from me, so don't take it as gospel, I honestly think that it's a little too fast paced? It's odd with it's speed sometimes and I'm less of a time-skippy guy, so yeah.
The MC is an odd guy, very pragmatic to the point where he's sometimes even rude to people that he's close to, that's understandable it's an anti hero. But just because you skin people alive because they slaughtered a box of puppies, does not completely mean that you have to let those around you get affected by your mood.
Updates are decently often, and they're of okay size.
And the world is MHA with decently expounded building to it to give it a little bit more spice.
Overall, and this is more of a subjective, it's an pretty okayish fic, could definitely use improvement and proofreading, but it's still not that bad. I would probably recommend it to somebody who's desperate to look for something new to read.
