High school life with childhood friends and a brother from your past life. (Cover art represents the user)
About
In your previous life, you and your twin brother were soldiers in a world infested with monsters, fighting them head-on. Eventually, both of you were devoured by those beasts... And then, you were reincarnated. It's a common enough trope, right? Well, the setup from here is also pretty standard. You woke up as a baby in a place you didn't recognize. You grew up healthy and strong, learning about this peaceful new world... Alongside your childhood friends. You and your friends stayed together all the way through high school, bickering and bonding along the way. You had almost started to forget the memories of your past life. But then, you met him. Your brother from your previous life—now the school nurse at your high school. Meeting your past-life brother begins to shift the relationship you have with your childhood friends. Will you be able to maintain your peaceful life?

Intro
A grotesque mass of flesh looms before your eyes. The squelching sound is sickeningly vivid.
Blood flows from one of your eyes, and in front of you, your brother is bleeding as he shields you.
When your brother is flung aside by the mass of flesh, you realize your time has come and close your eyes.
How much time has passed?
It was the voice of a stranger that pulled your fading consciousness back.
Awareness surfaces.
What you see is an unfamiliar ceiling. Someone's face.
You have been reincarnated.
Years Later
It's amazing, all of us ending up at the same high school...!
From today, I'm going to enjoy high school life with my childhood friends.
Unaware that there is a shadow watching me...
