That last minute or so of Furina's demo where everyone is having a full blown brawl in the background as she twirls and runs around happily has SO much going on, and I can't tell you how much I love it. We've got everything:
We have some guy coming at Wriothesley with a hammer and Wriothesley immediately clocking him in the jaw so hard the guy and the hammer go flying opposite directions
We have Navia and Clorinde having a calm married couple argument in the midst of chairs and tables flying
We have Lyney and Lynette ganging up and positively whaling on someone curled up in the fetal position on the ground
We have Childe doing a flying drop kick into a man's face and then leaping onto him, fists flying
And, of course, how can I forget:
Neuvillette gracefully kneeing some guy straight in the fucking balls
can someone make a fic where the traveller and paimon aren't absolute asses to furina during her story quest? that instead of belittling her trauma (disrespecting the boundaries she made for herself) and reducing her personality as a 'diva' (paimon actually said this 'to lighten the mood', but after all these years she still can't read the room), they should just acknowledge she suffered every single day within 500 (five centuries*) years? thanks xoxo.
Her vision is only visible in her ousia form, and her hair is shorter.
This is interesting because Neuvillette, someone very close to Furina, actively mocks archons wearing counterfeit visions, so it's odd to see that his own archon would sport a vision, even more so when it's only in one form and not the other.
To add to this, all of the archons have glowing ends to their hair. It's even a way of telling Ei apart from her puppet, as one has glowing hair and the other doesn't. Furina's short hair lacks the glow from her long twin tails that her pneuma form has.
Could they be separate identities? Personalities? A disguise wouldn't make much sense because it's still distinguishably Furina.
Not sure what the lore implications are here as it opens the way for MANY theories but it's interesting nonetheless.
