You gotta wonder why the Magia Trio are chasing them at all. They do nothing to people. They just turn up, and the magical girls are immediately like "evildoers, we will destroy you".
It's kinda like they deserve the torture they get...
Like, they don't seem to even be smart enough to notice Baiser isn't killing them even though she has every opportunity to.
Remember Baiser not the only villains in the story and her intension is to mess the magical trio
they been fighting monster before that and they know Beiser can create monster + recently monster destroy the city once so
