The Mellingo twins themselves!!!!
Cassiopeia (Cassie) & Mirabelle (Belle) are aspiring entrepreneurs who are usually underfoot at Gear Station peddling their wares alongside their partners Glameow & Buneary. Cassie operates a stationary and mailing business that sends letters and packages on the trains that can be delivered to the recipient by one of the railway pokémon for that special personal touch, while Belle sells homemade snacks and lunchboxes for any passengers that might need a bite to eat while on their journey. (They were inspired by their cousin Janus’s stories of working for the Ginkgo Guild!)
They’re the babies of the Subway (a title inherited from their older cousins, as all of them are 10 years apart), and can get away with being menaces thanks to being cute (a trick definitely learned from Melli, along with the importance of fashion).
