I've been reading a few fanfics in my spare time when I can. I've read several Naruto/Dragonball fanfics in the top 100 and some on other sites. Honestly, the ones on this site were pretty damn bad. The only good one I've read on this site so far was by Myumara, who seems to have disappeared off the scene. I'm happy to say this is the 2nd good fanfic I've read on this site. Let's talk about why. Note: I give 5 star review despite the scores written below.
Writing Quality: 4/5. It's unbelievable how hard it is to find a fanfic with good grammar. The author slipped a bit for a few chapters, but quickly recovered back to high-quality grammar. Also, the author isn't lazy. I read a fanfic recently where a fifth of every chapter was just listing the MCs stats on a system. Completely ruined the otherwise okay story for me on that one. Thankfully, the author of this book takes his time writing the actual story instead of pointless nonsense. Note for the author: Please learn the difference between your and you're. It's your most common mistake even though you're a fairly good writer.
Stability of Updates: 5/5. They're frequent.
Story Development: 5/5. We've got a mystery on our hands over Deku's new quirk. It's interesting and the author isn't sticking to the original plot like a mindless zombie. So many fanfics seem to do that. Good job author! Its a unique story with it's own potential!
Character Design 5/5 and 0/5. The author develops his characters well. Deku is maturing and growing as a person. Bakugo grew up very differently due to the new Deku. So, 5/5 on those parts. Why the 0/5? I'm a Deku x Uraraka shipper! What have you done you monster! This is the 1 ship that should never break! Lol. I'm joking (I'm not joking!).
World Background 5/5 and 2.5/5: The world building that the author does is done very well. So 5/5 there. The 2nd lower score is because you probably need to be an MHA fan to enjoy this. I don't think I could understand it very well without that background knowledge. That might be a given considering you'd only expect MHA fans to read this. However, I still like when a fanfic can stand on its own two feet.
