Has there ever been a time when mochi was so powerful and scary during a fight the team was scared of her?
YEAH!!!! maybe not "scared" like terrified they would kill her, but right after she comes back post-timeskip (actually it was the episode they go get lime back) she does an UNREAL show of power kind of spell, and doesnt break a sweat. no physical effects from the spells toll or anything. just goes about like nothing.
and they all have a short moment of reflecting and recall when mochi was still learning, she could barely fight taffy without her nose bleeding and passing out, and now she can wipe out 4 forrest giants in the blink of an eye. and lime especially is like oh boy. she uhh she got even stronger huh...
