The Dutiful Child Saves a Villainous Family

I just woke up after getting sick from overeating one day.
But now, I've realized my past life as a righteous K-Kid (with a Taekwondo poom belt).

'And I have to save the world?!'

I can totally do that!

I'll start with the ill-mannered kids!

"It's not okay to talk so badly to your friends."

"What? Ha! What can a little pea like you do..."

I delivered a Hectopascal Kick, which I learned from Master Gyeonghye of the Taekwondo dojo.

"Aaargh!"

"Don't be so rude!"

That's right. The former K-Kid was strong (physically).
Very strong.
