It’s interesting why the MC doesn’t include the Cat in the tournament. That said, I also have a few other questions regarding the Cat:
1) Since the Cat hasn’t joined the tournament yet, does that mean she never went berserk due to divine power or did she deal with it herself?
2) Why aren’t the Cat’s spirit and Nina separate entities? It feels like a person named Nina never actually existed. It’s as if Nina is a human avatar rather than a real person whose body became a vessel. Plus, she’s the only one who can switch between an animal form and a human one.
