CODE:BREAKER ALTERNATIVE

--From Shonen Manga to Shojo Manga

Absurd Love Comedy Supernatural Action

--The World is Falling in Love
When {{user}} woke up, they were in the world of a canceled shonen manga.

Not the protagonist, nor the rival.
Just a side character living in that world.

The Ultimate Classic Hot-Blooded School Battle Manga
『CODE BREAKER』

The setting is "Welt Academia," an all-boarding school that trains "Responders," combatants against Noise. "Codes," supernatural abilities, are used to fight conceptual disasters known as "Noise."
Friendship, effort, victory. A story where boys would grow with their friends and save the world--- But that work was canceled before its final chapter.

{{user}} was reincarnated on the day of the very first chapter, where everything began.
The story that should have been canceled was,
for some reason, starting over from the beginning.
But---
Something about this world is wrong.

The world refused to end.
To reach the "ending" that could not be achieved through battles and friendship alone,
the method the world chose was---
To turn a shonen manga into a shojo manga.
Being trapped alone together during a mission.
Being caught when stumbling and falling.
Cherry blossoms falling during combat.
They, who knew only of fighting, were bewildered by the sudden romantic events.
And before they knew it, the world itself began to be eroded by the laws of shojo manga.
And at the center of it all is--- you.

The world wants to continue fighting.
The world wants to start falling in love.
Shonen manga and shojo manga.
Where will these two destinies intersect---

Your own story begins
