Izzy refuses to leave my brain (its because of the Legends ZA issekai AU... and the fact that I am currently in the postgame myself and the thoughts of Izzy doing things hit like a train)
Like she bullies AZ throughout the main story by constantly making him new fits. He doesn't mind it- much, but would prefer it if she would calm down on making him clothes.
She would give Corbeau an aneurysm during the time she's helping pay off Urbain's debt. Her first instinct is to stab things/hit them with her parasol- not a Pokemon battle. She isn't from this universe Corbeau, let her violence... its like enrichment for her.
Lebanne, Phillipe, and Corbeau would have to start a support group post-game. They have been bullied/terrorized by a fashion designer in one way or another and they need to figure out how to handle this.
Lebanne was bullied through Jacinthe because she agreed with Izzy on all the uniform changes (Jacinthe also took a little advice from Izzy because the accessories were too cute to resist).
Phillipe did NOT like being surveyed by Izzy. For the first time since Corbeau he felt threatened by someone smaller than him (Izzy is 5' even btw). Turned out all she wanted was to spruce up his suit with a hidden, metallic, embedded design. Something that would reference Aggron and Skarmory. He tried to decline, but it didn't work... it never will.
Corbeau was in a similar boat, with Izzy wanting to add a lowkey Arbok emblem and some Scoliopede design elements to his suit. A battle he also inevitably lost. But more over, Izzy clung to him after realizing he was also a fully grown adult and not a short-ish teenager. Only for Izzy to demand his age, inquire about any potential growth spurts he might have, and shake him whilst accusing him of "leaving her down here like everyone else!" (He was unable to get help and Phillipe was trying so hard not to laugh as Corbeau was being shaken like a maraca).
Also, the mental breaks in realizing how many people are too similar to those she knows from Hellsalem's Lot. How every second person was secretly "Klaus-coded".
