Just wondering how everyone's mains and subs have (or have not) changed as the series has progressed. For me:
CT: Main - Rachel, Sub - Ragna
CS/II/CSE: Main - Rachel, Sub: Platinum the Trinity
CP/CPE: Main - Izayoi, Subs: Rachel & Platinum the Trinity
CF: Mains - Es and Izayoi, Sub: Rachel
How about everyone else?
