Ok so if your up to date with Yugioh Arc V you know somethings right. So I'm not gonna try and spoil things but just a warning I would go watch the new episodes of you not up to date then read this.

Today's topic Revival Zero, Reji mention this before they reached the Academia a few episodes ago. What exactly is Revival Zero my theory is returning the Counterparts back to their original state. Your probably like Penny what do you mean by original state, what I mean is I think that Yuya and his counterparts were one person originally same with Yuzu and her counterparts. I've seen fanfictions and headcannon a on this and I share the same opinion on the matter. Now for some evidence.

First up the new opening and ending.
In each of them you see a cut out version of two people a girl and boy and if you look closely you can see some similarities in the hair. By similarities I mean they have the same outline of hair the Yu counterparts do. Easier to show them explain so let me show u the opening Rights reserved to the rightful owners.

In this opening after Yuri's entrance you can see the camera move up at a picture of the Professor. Then two light beings kind of merge into each other, that my friends is what I think The original version of the Yu-counterparts and Bracelet girls look like. No for the ending.

After it Shows Yuya and his counterparts walking is sync towards the end you see the counterparts in the outline of yet a boy and girl. Yep that's right they appear again which makes me believe their trying to tell you something.

Second the rumors of Yuya and Yuto not separating. You see I heard rumors that their not gonna separate so maybe the professor wants them to stay like that because one counterpart is already fused with Yuya. I dunno this theory has holes in it but that's sounds somewhat like it could happen.

Third The bracelet girls
Why would the professor want to kidnap a bunch of teenagers. Well like Reji said before their a part of Revival Zero. So with that I think they also have an original form...... Don't judge I know that argument was small and stuff I haven't thought about it much ok sooooo onto why I think the professor wants revival zero.

Well for starters I think that of all of the counterparts do end up fusing together it could potentially bring the 4 dimensions to merge again. Serena said that's what the academia wanted in the first place maybe The professor wasn't completely lying when he said that. So maybe he wants the dimensions to merge so he could rule all of them or something.

Another thing maybe The professor wants them to merge together so they could be the ultimate weapon or something along those lines.

Practically all my theories are the professor using the original forms of the counterparts to take over the dimensions.

That is all the stuff on my theory, comment below and tell me what u think. Til next time bye
