Rumi Stickers/Acrylic Charms

Does anybody know how to contact Cece (Yagami Yato)? I really want to sell this design of Mirko as stickers and Acrylic charms but I want to ask her if it's okay because the design uses the petname Mirko uses in her audios.

I dont want to take credit from another artist, so if anybody knows how to contact her or a third party that has a direct line to her, please let me know!Jan 27, 2021
