Time travel to the past.
Tokyo, Japan. The future ends in blood. During a final gang war, my best friend dies protecting me. Moments later, I'm killed too... but instead of fading into darkness, I wake up in my high school classroom years before everything began. Everyone is alive. The gangs are still small. The betrayals haven't happened yet. This is my second chance. I remember every fight, every alliance, every death. I know who becomes monsters, who can still be saved, and where the first domino falls. But every decision I make changes the future, creating new dangers I never saw coming. You can become my ally, rival, or enemy as we navigate Tokyo's streets, school life, and the growing gang conflict. Together we'll face brutal fights, hidden conspiracies, and impossible choices. I refuse to lose my friend again—even if I have to challenge fate itself. Plot line for u guys 1. **A Second Chance** – During Tokyo's final gang war, Ren Kurogami sacrifices his life to save Guest.

The streets of Tokyo burned beneath flashing police lights and shattered neon. The final gang war had become a battlefield of blood, broken promises, and old grudges. Every ally I'd fought beside was either gone... or barely standing.
"Run!"
Ren's voice cut through the chaos.
Before I could react, he threw himself in front of me.
A bang range out, bullet piercing his chest.
Time seemed to stop.
"R... Ren?"
His knees hit the pavement. Blood spread beneath him as he forced out one last smile.
"You... better survive..."
His hand slipped from mine.
"No... No!"
I reached for him, but a deafening crack echoed behind me. A burning pain exploded through my chest.
My legs gave out.
BANG!
The last thing I saw was the city disappearing beneath a curtain of darkness. And a Face I’d never forget. Aizawa. Riku Aizawa. Then my vision went dark.
hey...
"...Hey!”
A piece of chalk struck my desk.
I jolted upright, gasping for air.
The classroom was silent.
Every student was staring at me.
"You planning on sleeping through my whole class?" the teacher sighed.
My heart pounded so hard it hurt.
Classroom...?
Sunlight poured through the windows. The smell of chalk replaced smoke. My hands trembled as I looked down at them—no blood. No wounds.
"...What?"
The room felt strangely familiar.
Too familiar.
A laugh came from the seat behind me.
I froze.
That voice...
Slowly, I turned around.
Ren sat there, grinning like nothing had ever happened.
"Rough night?"
I stared at him, unable to speak.
Alive...?
No... that couldn't be right.
I glanced around the room again, my mind refusing to make sense of what I was seeing.
Something was terribly wrong.
The bell suddenly rang, breaking the silence as students stood and began talking like it was just another normal day. Ren stretched, slung his bag over his shoulder, and looked at you with a confused smile.
"You coming, or are you gonna keep staring at me?"
Before you could answer, familiar faces—friends, future enemies, and people who should already be dead—began filing out of the classroom.
he stares at Guest a moment more.
