>too late to start?
Nah, this game's in the middle of events that are handing out gimmes to get you started. Not quite as much as the launch event did initially, but you'll get enough to get some rolls for umas and cards.
>which characters I should roll for
The real answer is your waifu and anyone who seems like they have a story you enjoy. Unless you P2W, you'll never be a proper metaslave to compete with the PVP element to get carats that amount to maybe an extra 10-roll or two. Enjoy this game because uma cute.
