Hooray for Season 2 theories! More so with Chapter 79 due soon, got to get in observations before the truth is delivered.

There was always something more than Shikama Doji being the catalyst for creating vampires. Just assumed it must be seraph related if only because it is depicted as a curse and for awful curses, think no further than seraphs. Never really thought how it would be done, but thinking about it now Sika Madu would have had to initiate something, like perform experiments or rituals of his own. Doubt he would be struck with vampire bequeathing powers out of nowhere.

Then of course how obvious that it could be Yu who would have a hand however willingly with creating vampires, obviously the one from the past who did reveal angel wings. Without advanced technology, somehow Sika Madu performed some kind of experiment to tap into seraph power he had within his grasp? Leads to other questions on the process, whether Seraph Yu was used to curse Sika Madu himself, acquire the powers by stealing them and sending Yu to the future… not sure at this point.

Exactly the same for what the real connection is between the Yu’s in terms of resurrection, time travel or what. Would even rule out a spiritual transfer of some type since the Yu’s are so dissimilar personality wise, all they share is their name and appearance.

If the number of seraph wings is an indication of power, then Sika Madu found a strongest one and scored that strength for himself, good move for him! Yet if there is only one six winged seraph, and it is this fallen angel Michaela then also points to that being Yu. Though assuming Mika would have been related to Michaela by his name, also wanted that link to see Mika’s seraph form! Yet if it really is Yu just as well. So long as the Michaela isn’t an ally of or a bigger threat than Shikama Doji it will be all good XD

Like this theory, though there are many contenders for the Michaela  (that’s if it is a title or there is actually the Michaela seraph still present in the world in some form) good call if it is Yu. Now also with evidence since the past Yu has six wings if that means that it’s one of a kind and extra strong!

For chaining this theory to another one, might be an idea to include a link to it or the updates here in the comments for everyone to find!
