This is good! Keep it up!

Here is a name for issilei's sword JOKER MEMORY SABER.

Still idiot for make a name

hey there idea Crossover for you
guilty crown and Kamen Rider Zi-o
Shu Ouma as Kamen Rider Zi-o

You're make me cringe with that typo/false name -_-

Hi, this has serious potential. Try to get a beta reader to correct the names and stuff... this seems good

God has been reborn as the True Gaia Memory. Makes sense, and it would explain why Memories can actually choose who is 'perfect' for them.

will accel be show them selves? vali is eternal so now we just need the bike rider, also, nice use of gosei knight

You do realize that Google and wiki exist for a reason right? Why the fuck are you not using them? And again... Do you not proofread your story before posting it? The horrible grammar is every where.
I'm not trying to bring you down or anything but... You had months to look through your story! But you didn't look through them at all!
And if you can't remember certain details... GOOGLE IT! It exist for a reason! And for some unknown reason you aren't using it at all.

The name of The Prison Dragon is Vritra

Looks like you are changing a lot of things from the canon story...
Like... When writing your story... You should always mention certain details that will be changed. Or else we will be wondering why such changes are made. Especially when you only release a new chapter in like several months.

1. making Issei's parents jackasses.
2. Issei's friend somehow being so obsess with power all of a sudden? No proper explanation I see.
3. All of a sudden he's getting his Peerages so early? Why? You don't really explain anything at all.
4. You don't even know the Evil Pieces value at all.
Pawns like you said are a value of 1. That's why there are 8 pieces of them. The Queen is worth 9 pawns. Rook 5 , Knight and Bishop are 3 each.
You can't suddenly change the value of the pieces as you see fit. You still have to follow some part of the Novel or anime... Whichever one you are using..

"If Pawn has 8 piece then they equal to 7?"
What kind of math are you even doing? Follow what is given in the wiki!
You can't suddenly change the numbers of the Evil Pieces System. That is something that you can't change without any explanation.

Why would you even count how much they are worth together? Makes no sense.
All together there are 15 chess pieces. 1 Queen, 2 Rooks, 2 Bishop, 2 Knights and 8 Pawns.
But if you were to get technical about how much pawns altogether they are worth...
They are altogether worth 39 pawns unless they are mutation pieces whose worth are undefined.

At the very least do something about the grammar and spelling errors. Since all the chapters are kinda filled with them... No sure why no one is saying anything but just wanted to let you know.

Well I have said my piece... This isn't a flame. Just want to let you know what is wrong with your story.
I think pretty much others are saying that same thing... Proof read your grammar and spelling mistakes. The Wiki for DxD exist for a reason. Because it seems to me that you didn't read the LN but watched the anime instead.
And again this is not a flame.

I want to say gosei knight, but Im not sure

Did you have to make Issei's parents into assholes? They were not like that in canon.

interesting path, looking forwards to go-busters and uzumaki ghost being updated and maybe To Soar Like an Eagle

Why didn't you update this? I really like it!
