Flayn, her own powers

Flayn was sick of being treated younger than she actually was. Not only was Seteth being his usual overbearing self, but everyone treated her like a naive child. She was a 1000 year old Nabatean, thank you very much!

Flayn decided to use her Nabatean powers to change things for herself. Starting with her girlish body. Sure, people thought she was cute, but she wanted to be sexy.

"My body proportions are now the boobs of Professor Byleth, ass of Hilda, and height of Mercedes," she declared. She watched her body shoot up, her bresats and ass expanding. She was cute before, but now she was sexy.

"Brother would probably kill me if he knew I was using my reality bending powers," said Flayn. "But I'm done being the 'innocent' little sister."

Her powers also allowed her to make changes and for those changes to be viewed as normal, so no one, not even Seteth, would question her new body.

Flayn skipped off, ready to cause chaos.
