if my cat at home turning into dragon of calamity, that world is fucked up.I guess it does make sense that a family pet would also get isekai'd, if truck-kun also hits them.
Imagine your cat/dog at home turning into a dragon of calamity.
In my case, my dog is already a calamity under the right circumstances...
most cat are asshole and love to break things and and act innocent.. imagine that with bigger body and powerful magic. he will break the castle just because he can.
