I Took In a Little Girl as My Mom, Then Beat the Gods to a Pulp

Good news: I transmigrated, and got a mom for free.

Bad news: My mom is a little girl, and an S-rank witch wanted across the entire continent.

Even better news: I awakened a System, and I can get stronger just by being filial!

Even worse news: This System is clearly messed up!

[Scene One: I protect my little-girl mom and get stronger, but I have to say "meow" whenever I speak!]

Captain of the Judgment Knights: "Witch! Prepare to die!"

I slap him flying, then turn back to my mom and say, "Mom, I'm fine, meow~"

Everyone: "???"

[Scene Two: I fight through a tide of rats for my little-girl mom and get stronger, but I have to praise her loudly!]

Me: "Mom's eyes are like stars! Mom's hair is like the Milky Way!" (I punch the mutant rat king to smithereens.)

My little-girl mom: (blushing) "Y-You can't just say things like that!"

[Scene Three: I help my little-girl mom snatch a secret medicine and get stronger, but I receive a "Rule Erasure" item and 200 points of Agility!]

(Wait, does this one have no side effect? What a bargain!)

Looking at my little-girl mom in my arms, happily clutching a honey cake, then at the Church, nobles, and bounty hunters outside, all offering rewards for our heads...

Fine. For Mom, I'll put up with any crazy sickness!
