I guess this is the ending of this line of events I guess. Good luck in your next work. :)

This story is really good. I was just looking for some Arc-V fanfics that weren't trash and I must say I'm impressed. The idea of using the LSD kids as the main protagonist of this series is extremely refreshing and the plot too. That last duel agains Qrowley was quite original too, I was just wondering how the Hell they were going to win against that unfair field. And then I found out that you had made a precuel with that Shadoll incident so I'm going to read that too.

Just as a side note, after Masumi said the phrase "wasn't Gem-Knight Paz." I could only see that scene with Kakyoin's main theme.

Don't they still have phones?
And what does Hontoka mean again?

With Solid Vision being immune to everything but itself, how would Zarc v Goku go? jk of course :)
A great start to another 1v multiple duel, my favorite type of duels! (just look at how many of them I have in Arc-VRAINS)
I generally only use the initial Translation, when
A. the card appeared in my story before the Official one
B. I'm too used to the 'sub name', like with most Action Cards, though for Skulldeat I stuck with it because it sounds cooler ;)
As expected the first strategy against Seika Fails, and they have to pick a different one, unlike in VRAINS where Yusaku is like "nope I'll break this lock use Storm Acces/Link summoning after all" every single time or the actual Arc-V where every attack lock predictably was broken the following turn.
Though it's interesting how different we write duels, because I usually write the duels as I write the chapters and only know of a few key Events that need to happen beforehand.

for the final scene:New World Order - Instrumental Mix Cover (Danganronpa)
Now to the chapter:
You know, Hotenes point about the lack of police involvement raises another question: Shouldnt dueling armies either play Overpowered (FTK or lockdown) decks or cards that would excellent war machines thanks to Solid Vision?
And it seems like the final duel of this story will be a few v many duel of Masumi (and partners) against Seika, Seika and the creator of Seika or just the creator of Seika.

So the fact that duelist dont Need to explain their Cards and that you cant read your opponents Cards in the Anime is a Major clue in this Story?
And I cant help, but imagine a conversation between Himika and Donald Trump. ;)
Also, is there a reason, why normally you use Sub names and initial translations, but use the Name LID instead of LDS?
And since your OC Cards will be compiled at the end of the Story, instead of every chapter, it wont take a huge number of chapters to finish, right?

Hey did you read my PM?

I think your works, especially this one, are seriously underrated. I think it's awesome how you have expanded upon the story of the LDS trio, characters that were-I believe the term is-"put on a bus", after season one. Those characters were probably implemented into the story just to act as temporary rivals for some of the protagonists, but you have expanded their world to a great degree. The way you write the duels is perfect, and I liked how you introduced archetypes such as "Shaddolls", "Qliphort", (correct me if I spelled that incorrectly), and "Inferniods" into the ARC-V universe. I hope someday you will continue this exciting chronicle, for it certainly stands apart from most of the other ARC-V fanfics out there.
