villain's maid, villain's savior, villain's mOTHER WHAT ELSE OMG
it's a nice pace though compared to just being the villainess themselves

There is an manga for isekai into a op fluffy dog, for a princess not a villain's though.

Idk if you wanted this but I shall link it for ya.

that's it. I can conclude she exists for fan service. WE DON'T NEED IT AUTHOR

Story is really good though. It has potential but the dead give-away of a possible harem or romantic interest is so unnecessary by the way Isabelle was blatantly shown a lot. She's introduced as a strong mage but is unfortunately poorly written. She could've been a good partner but nah, let's let her cling to him instead
Hopefully it gets better for the future chapters but like we're already at chapter 16 so
can i pleaseee keep a pokyu in my pocket as well
