The Dutiful Kid Who Saved the Villainous Family

One day, after overeating and lying sick in bed, I opened my eyes and realized... I had awakened from my past life as a righteous K-child (Taekwondo black belt)?

"Wait, I have to save the world too?!"

I can totally do it!

Starting with the unruly kids!

"Don't speak so badly to your friends."

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

I performed the Hectopascal Kick I learned from Grandmaster Kyung-Hye, my Taekwondo instructor.

"Ughhh!"

"Don't be a jerk!"

That's right.

The former K-child was strong (physically).

And very, very strong at that.
