I hope you can improve your grammar ASAP, some tips for you: try to read it loud by your self and I bet you will find some conversation and paragraph is odd, I'm definietly not expert but I can somewhat know that the word you used is wrong.
I can't say much about world background and story development since I think its still too early to judge it.
the character design is too bland, I don't feel the characterization or maybe some say the "soul" of character at all, try read other works maybe you can take some inspiration from them.
and good work, hope you can do it better for the future chapter.
interesting I have not seen a story in a long time like that I hope to see how it continues to develop interesting I have not seen a story in a long time like that I hope to see how it continues to develop, I love how the plot goes sincerely from I give 10/10
OK the idea is not bad but the grammar is so shit that you have no idea what is going on there, more or less.
First of all I can only recommend to the author to learn a little more English and to get someone to check the grammar
Unreadable, it's honestly just a mess. The idea is interesting, but the execution is terrible. Everything from grammar to the lack of punctuation mark's to wording to sentence building, is just straight up terrible. I have problem's understanding if the mc has knowgledge of the world he is in because the grammar is so bad! Just read the chapter called "Issei" and you see what i mean, it just doesn't make any sense what-so-ever. I could rant more, but it would take day's if i start to nit-pick. But one thing which scream's bad fanfic, are these chapter's with "15k word's". They just scream trash! Anyway, why i don't give one star is because the idea is interesting and im in a good mood.
Writing Quality: Straight up trash, it's like a 5th grader wrote this. Native language or not, this is bad. Like really bad, not MTL level (i think) but still terrible. [1 Star.]
Updating Stability: I don't know if it's going to be consistent, but im giving the Author the benefit of the doubt. [4 Star's]
Story Development: Development? There is none so far! It's just time-skip and another time-skip and another time-skip. It's rushed af, he is already rich. Is basically already Op without any training, typical manga writing which just got glossed-over. Has already a secret organisation, every girl in school love's him, and all that repetitiv boring bs.[1 Star.]
Character Design: It's Highschool DxD, the only oc is the mc. But beside's "very cute boy" we don't know anything. Ah, i think his hair colour was white? I don't really remember. [1 Star.]
World Backround: It's Highschool DxD, so yeah..nothing is added, it's simply DxD. [2 Star's]
[P/S": I read this this in like 20 minute's, so if you want to see how good this is. Then good luck! I wish the Author good luck, like i said, the idea was interesting. But the execution was horrendous.]
well, i will give brief review about this ff.
stability update is good.
world background is good.
character design and story development is EXCELLENT.
mc is not fucking SIMP.[img=faceslap]
mc create organization and somehow became a like of dangerous organization because DXD world is kind of F ucked universe so he can protect themself especially devil which want to force to reincarnating him.
this story is not for SIMP READER which LIKE TO READ GOOD DEVIL DXD.
instead its for reader whoch want to read dxd from realistic pespective.
