I will be honest, while I want the cast to grow and expand, with new stories and all, I don't want Volume 2 to become too big for its own good. Introducing new character when our three main casts are already unknown in many regards might weaken any character development for them, as all will be focused on making the new characters seem interesting and cool. Velvet's team is probably the most I would go with right now in terms of predicting the number of newcomers, as we have the villains (Roman, Cinder, and her two lovely associates), three teams (RWBY, JNPR and CDRL), Penny, and Sun to also expand upon. Expand upon the teams, and core villains, then introduce more new characters.
