The grammar was very **** at first and still is, but a little better, however, I find it excruciating to have to continue reading someone who uses "bcoz", "coz", "u" and other text talks phrased. It ruins what little immersion I have in the story.
The character interaction is hilarious and my favorite part of the series, especially from Quatz and Hope. I feel like this entire fanfic is a joke and should be treated as a joke as it makes it way more enjoyable to read. At first, I treated it seriously and got frustrated by how stupid it was, but when I saw it as light-hearted comedy fanfic, I enjoyed it way more.
However the joke is ruined when the author tries to make it serious, it just doesn't work. To make the fanfic serious the characters and the relationships must first be properly established and make the audience become attached towards them, which I couldn't do, due to thinking that it was a joke the entire time and the fast progression of character relations with no real emotion in them.
I found it very interesting when he was in Highschool DxD world, but when he went to Fairy Tail, I just found it slowly plummet as the story tried to make it serious. I just can't get attached to an MC who had a personality change for no reason, which got rid of all my favorites to his character. It's annoying to see an MC who doesn't want to see bad stuff yet continually does bad stuff and does nothing to stop said bad stuff. His character turned to **** is what I'm trying to say.
I hate how his emotions are all over the place. There is literally no reason for this at all. It has been stated that he can control his emotions but has not shown control in any of the situations where he needed his control. I'm pretty sure that the reason he cant show his emotions is that he thinks that showing emotion is a weakness. What bull**** is this? Get this mother****ers emotions under control already.
Whilst I love Quatz, I kind of hate red. Red is just a helicopter mom and no wants that. Also, what's up with the system? She has been a minor role and has already been forgotten by most of the characters that know of her. She has been pretty much unneeded during the whole fanfic and is rarely used.
I liked the interaction between Quatz and Red because of their funny interactions, however, as I kept reading I realized that it's basically Issei and Ddraig with some personality tweaks here and there. They only really change when they reach Fairy Tail which I actually hate due to the MC not being in control of his emotions and acting like this weird peace lover that doesn't want anyone to get hurt, it feels like I'm watching someone who is always on the fence about something and it's frustrating to read.
I also think that going to different worlds was a bad idea, I get it, he needs to control his power, however, I feel like going to a place where it's harder to control his power is a horrible idea. It would have been more satisfying to watch him go there when he himself can control his powers and possibly turn into a dragon.
Red as a character is ****. I have seen where the author wanted to make some character development moments for Red and Hopes relationship but I thought it was banter at first so it really wasn't emotionally connecting in my mind, more of a rushed and badly done story.
I'm gonna end this review here now as I can't be bothered to type anymore and I feel like I have repeated the same stuff over and over again so I'll just give a quick summary of what I hate. The Grammar needs improvement but the author has gotten better, it all went to **** when he went to fairy tail and I feel like the author wanted to make it serious and somewhat dramatic halfway through the story when I thought it was more enjoyable reading it as a comedy, I also thought there were quite a number of inconsistencies in the story so the author might want to go back and re-read or just skim through.
