KO One: Guardians of the Light

Brothers? Family? Now that we're here, let's experience everything together and protect everyone together. Fight!!!

P.S. No female lead, and the original couples remain together. The author is a student who only gets to use a computer once every two weeks. This is my first time writing, so please bear with me.

This novel and its characters are entirely fictional. Any resemblance to real people or events is purely coincidental. Do not imitate.
