Robot Magical Girls Kasey and Belle

Wy has arrived to wrap up 2020 and bring in 2021 by giving you some new characters he came up with. Meet the Robot Magical Girls, Kasey and Belle.
Kasey is a 20 year old Robot Magical girl who was born as an MGX11, then modified herself over the years. Her current form is her 5th. She's sweet with an Attitude, Experienced Magical Girl. My Ideal voice for her would be Anairis Quiñones.
Belle is a 19 Year Old bodiless AI she befriended & developed a sisterly bond with & helped her get a physical robot body. She's a strategist & Genius. She's also a reliable Friend/Sister to Kasey. My ideal voice for her would be Cristina Vee.
I'd compare both of them and their relationship to TOM and SARA of Toonami Fame. I hope to do something with them one day. I got ideas for them. I hope you like them.
