Purirun's in a weird place right now because of her memories from episodes 1-17 have been gone for 3 episodes straight. She does feel like a subtly different character. While the character growth she had from 1-17 wasn't all that extreme on paper, it's a big enough aspect of Purirun that it just being gone is jarring.
Meanwhile, Meroron is the same character we've known and loved. The catch is that the current circumstances encourage Meroron to double down on her negative traits instead of at least attempt to get along with the others. It's fun.
