Ok so, let's start cooking what I think Mora's ability might possibly be....
Spoilers ahead 💥
I think based on us seeing a freaky ramus baby thing both just before when we meet Mora and when Lucas and Miura discover how Rami are born, there's definitely gonna be something here related to time.
And we all know how much Mizuki Sora loves fucking with time.
More accurately, I think it's something to do with reversing time! For an example reversing time on a broken pot to fix it and get rid of imperfections based on weathering and age. Then in a situation where he Flowers he might have the ability to do a giant time reversal much like the way the Futurists came back to present day.
This is based on VERY lose evidence so further input would be brilliant if people can find more evidence for and against 🩷
Back to the theorising- IF he does have an ability along those lines, that explains why he was so vocal about not wanting to hit Lucas if they wanted to take him back alive. This could also apply for like- Super Mega Disease Ability that Kills You Now, but why would there have been a focus on the freaky branch baby back when we met him? That and- it wouldn't be a fun way to extend the plot.... But it would make sense they would want to target Lucas and even Zoe, as Lucas has been said to have the ability to change the tide of war on so many occasions- and with Zoe's time stealing there's gotta be a way you can mix Time Reversal and Time Stealing into a super op ability.
Also if Miura is gonna turn into a freaky branch baby I'm gonna cry so hard I pass out 💔
