*Spoiler Warning* Full Synopsis, Questions, & Suggestions

This is the full synopsis, had to cut off parts because it didn't fit. 

Ichijou Ryu, eldest son of the Shuei Clan Yakuza and older brother of Ichijou Raku, finds himself with memories of a past life and within those memories, he is able to understand that he reincarnated into DxD with a Soul System which gives him a unique way to power up in the danger-filled world. Finding himself in a mash-up of immense proportion, he will need to get it together as the balance of each power keeps tipping. What challenges await him? How strong are the threats? Will he be able to cope with the sheer inconvenience of spontaneously transporting/reincarnating/transmigrating into different worlds to answer a soul-call? How strong will he become? How long will the chapters be for that world before going back to his main? 

-------------------------

The MC may be a reincarnated soul, but because I wanted him to fully integrate himself into that world, he retains the personality he cultivated in the world. Of course he will be childish and make stupid mistakes because of this, though hints of maturity will still shine through. I'm not some 4D chess kinda dude, so the antagonists and all those cunning people in said animes will maybe fall short so I'll try my best. 

He will obviously have bullshit luck (sorry but this does include getting ridiculous powers, gacha luck [only for like the beginning idk if I want to keep it], women but I hope I can make them all unique wish me luck, and other such events), knowledge ofc with no baggage from his previous life, stupidly cool system that I got inspiration from countless novels I have read here, but because of that I gotta research and make it make sense, and this will defintely be an AU. (cuz of the mash-up haha) I'm saying all this because I find it so cool to have a bunch of characters from different anime interact with one another, though having them retain their personalities will be a lot of work... anyway, he will definitely be overpowered. 

--------------------------

Alright, so critique is welcome and definitely comment whenever clarification is needed or you want to suggest something. Because as much as I want to be this amazing author-like quite a bit of people are on here- I am definitely not, so all the help for making this passion of mine a reality is welcome. 

This will be one of many fanfics but it's already a massive undertaking, so I'll do my best to upload (don't count on it to be everyday because work is killing me rn). With that being said, Patreon is tempting, but with how I might be inconsistent, it'll pronbably be best saved for later. Since I might just draw my own stuff, nsfw ofc but also sfw.

Anyway, I shall definitely add my discord or create something so you guys can share stuff about this. 

I'm also not the most imaginative so I'll give credit where it's due, honestly I'm at the point where if people wanna write a chapter for this they can go ahead and I'll write their user at the top. I'll do my fcken best though, this fanfic stuff got me pumped and I'm always sad asf when authors disappear (understanable they have their life) but dang the stories I've read from them are peak. Right! If you find something that looks familiar from another author then yes I have taken inspiration from them, feel free to point it out like a way for it to make better sense or a way where it won't be obvious, though I think it'll be integrated enough I hope. Shit dude, some of these people have insane imagination and it coincides perfectly with their story (like power ups, weapons, systems, characters, etc etc.) Epic of Caterpillar, Chrysalis, Endless Path, to name a few. Fcken superstars man. 

--------------------------

This is a Fanfiction I do not claim ownership or credit of any of the works here or their characters, only My OCs so support the release of those, ngl Ima definitely buy myself the Nisekoi series soon. 

This novel may or may not accurately present the personalities of the different characters. Some protagonists and characters may not be here depending on who they are and if I can incoportate them. This is a wish fulfillment and it might be a bit excessive but this is the story I envisioned. Right, some of the character descriptions will be from Wiki and Fandom, this includes explanations about items/abilities/people/etc. I might forget to add chan or san etc when the character is talking in the first person so I apologize.

This will be my rapid fire questions.

Right, so only answer these once I finish publishing chapters and get to the part and when you have read it, you can skip this if you haven't.

Anyway, depending on what people say maybe I could change his scared gear, specifically make it an OC dragon with powers over the soul.

How to properly explain the soul upgrades and the mana core upgrades and then the tiers? Complete removal? Or how do I smoothly put them in? Perhaps I can say that the long ass names is because his soul system makes it easier for his own soul to be easily influenced, like when absorbing power. I definitely gotta expand on why the dimensional gap opened but what would be a a good way to describe it?

How do the chartacter personalities feel? Change something? Emphasize a certain aspect or keep on writing them how I feel like they should be in this AU?

Any changes to my protagonist? I ain't gonna be picky tbh, enhance/decrease something about Ryuu? Does his personality seem consistent throughout the chapters?

Right I need lots of ideas about sacred gears for the girls, of course a select few of them, for right now I have a list of all the women for the mash and the different world. I'll post it later. With that being said, it might be better to just leave it to the ones mentioned already. Like for Shouko?

Any ideas to what other anime I should mash into this crazy world? I won't say what the others are until characters appear but give suggestions and I'll let you know which ones are there and which ones are not. Keep in mind I may not have read or watched said anime. Light novels are welcome, I'm tempted to add "The magic in this other world is far too behind." I gotta reread it though, ooo another one could be "I saved too many girls and caused the apocalypse."

Now for a specific chapter, you guys might comment on that chapter but I'll also put the question here , how was the summoning of Jibril? Shall I add a Jibirl POV? Too much of an aburpt change on how she carried herself? What could have Ryu done differently? or used as leverage? Should I add on some stuff or cut out parts or change it completely?

IMPORTANT!!! SPOILERS BUT I AM IN NEED OF SUGGESTIONS

I am saying this is important because it will involve me continuously writing quick drafts in the draft section. I already have it till 100 chapters.

Of course, I can modify them but right now at the moment, Ryu will finally enter his abrupt call of the soul in the 100th chapter. 

I have two options that are honestly pretty damn good, like background-wise and nice ideas for his powers or at least one of them. While the other is a cool AU idea. 

Super Mushroom World (I'm calling it this instead of Super Mario World because he does not exist hence the AU)

Konosuba World

Do you guys have any other suggestions?

I classify these as low-tier worlds....

Damn, I also gotta write down their classifications. perhaps they are in between D-B Tier? Considering the wacky power scale and the comedic action it has. 

So it'd be 

E - D - C - B - A - S - SS - SSS - EX. ----> I H G F E D C B A S (with + and - respectively) *Suggestion by Psan 

Do you guys think that's good? I'm mostly following a certain fanfiction I love. 

I think I have other good ones. However, I will need help on which ones to go to in order in proportion to his power. It also might be a good idea for him to finish the world and then instead of going back to the main world he ends up jumping to another (I'm thinking the maximum would be 3 before he goes back, if not then 2 is good.) 

In Another World With My Smartphone (mostly to interact with the gods, interact with the girls, build up his political mind, and interact with different people)

Demon Slayer (Practice his control over energy swords maybe? or maybe his boosted gear changes to suit his needs? or do I just give him another sword to soul bond to, kinda like that one Demon Slayer fanfic, the awesome Moon weapon they have)

Seirei Gensouki (Mostly because it's an awesome world with spirits)

Arifureta (definitely a good way to train against monsters and build up his mentality, overpowered waifus are always a plus)

Danmachi (Also a good way to interact with gods since they won't use their arcanum and a way for him to build himself up in the dungeon along with gathering powerful allies, though the journey would long as so I'm not sure, probably in the future would be good)

So I'm a Spider, So What? (this is one is gonna be easy and hard. I love the world-building and the way the lil spider gets op quickly asf. not to mention Ariel and Sariel. They f*cken deserve to live happy lives like wtf. an awesome way to gain power and maybe try out him starting as his dragon form so he can unlock it and get used to it. But if I am gonna do this then it'd have to be either the second or third world. He still has to experience the call of the soul in a human form. Plus D is gonna be a problem, sure I'm the author but even I got the chills when reading the novel. ) 

Keep in mind though, that I'll be needing your help in getting important knowledge about the anime worlds. I'll be reading the novels though, and watching the animes. it'll take a bit before I dive in. DxD is mostly what I remember from the anime, websites and what I picked up on in fanfics lmao. 

Anyway! 

I'll add more as it goes on. Thank you very much everyone!
