Here is a question how did the Canopy Kingdom survive all the surrounding nations forming up to attack them after Nancy's wish. Because in
canon ALL Skullheart wishes, (that have nothing to do with becoming the Skullgirl, because the Skullheart already has a rule-set on how you become it, so wishing to become it just means no other wishers were granted and it's rule-set on how pure the wish was goes into play), twisted by the heart or not are granted immediately, (see Filia's ending).
So by canon logic all the countries would feel the immediate need to attack the kingdom.
And the time-frame of at least 9 months or more had to occur between the wish and Nancy Skullgirl, (start of war end of war) because she had to have gotten pregnant during the Skullgirl transformation process.
That means the least amount of time of the war would have been getting pregnant after wishing on the SH
on the same day, then
right after giving birth to Umbrella immediately she would become the Skullgirl.
So given that time frame and multiple surrounding countries attacking all at the same time on the Kingdom I would think that it would be nei impossible for Canopy to stll exist!
BUT!
I do have one theory on how it could have survived.
What if during that time frame knowing the oncoming threat is when the Canopy government turned to drastic measures.
What if during that tie frame they created the
living weapons! (The creation of which is theorized
here!)
It makes too much sense, think about it, their power would even out the playing field long enough for SG Nancy to take the charge.
And in Cerebella's story her living weapon of Vice Versa was passed down to her by her parents that are dead! (
Dead by fighting in the war!) and that would explain the absence of her parents and why she of all people outside of the military would have such a dangerous weapon.
(ps. this theory was made on Thursday night streaming event.
Theory Thursdays!
And this will become a Skull Lore Theories video!)
