Defender (Luka Couffaine x reader)

"You picked a new holder of the ladybug and cat miraculous?"
"Yes, a girl by the name of Marinette, and a boy by the name of Adrien"
"Good thing I finished training when I did then"
"You're aware of your mission?"
"Protect the miraculous holders"

Y/n L/n, Master Fu's granddaughter, just returned to Paris from her training as a guardian, not of the miraculous themselves, but of the holders. Her Kwami, the kitsune called Yae, has been watching over the holders for centuries, and eventually was passed down to her by the elders she lived with. She holds the power of transformation, which allows her to turn anything she wants into something else. She begins her life as a normal teenage girl, making sure to always be near Marinette and Adrien, but there was something she never anticipated. Ladybug temporarily giving miraculous' to others, and beginning to fall in love with one of them.
