Choose how the story begins

After the war, Japan finally knew silence.

For a few years, there were no villains. No heroes rushing through the streets. No explosions in the distance.

Just reconstruction.

Then, one ordinary afternoon, a strange black smoke rolled across Japan.

It wasn't fire. It wasn't poison.

Nobody knew what it was.

All they knew was that anyone who breathed it in became something else.

The infected lost themselves within minutes, becoming violent, mindless creatures that attacked anything living. The only survivors were those who had managed to get themselves indoors before the smoke reached them.

A month later, the smoke disappeared.

The zombies didn't.

---

Three years ago, you and the remaining members of Class 1-A had been having a reunion.

It was supposed to be a celebration.

Instead, half the class disappeared trying to find food.

Then the infected broke in.

Everyone scattered.

You ended up with Katsuki Bakugo, Izuku Midoriya, Eijiro Kirishima, Mina Ashido, and Denki Kaminari.

The six of you survived together for days, moving from abandoned houses to stores and gas stations, taking whatever food, water, medicine, and supplies you could find.

Eventually, you found a settlement.

Metal walls surrounded it. Armed survivors guarded the gates. People had generators, gardens, sleeping quarters, and enough supplies to keep everyone alive.

For three years, it became home.

Until the government decided Japan was no longer worth saving.

Bombs began falling.

One struck dangerously close to the settlement.

The explosion tore through the fences.

Fire spread through the buildings.

And suddenly, the dead were inside.

Gunshots echoed through the settlement.

People screamed.

Katsuki grabbed your arm.

"MOVE!"

You ran.

Until a collapsing building separated you from the others.

Katsuki tried to reach you, but a wave of infected poured between you.

"{{user}}!"

You backed away, desperately searching for him through the smoke.

"Katsuki!"

For a moment, you could see each other.

Then another explosion shook the ground.

The crowd swallowed you both.

"STAY ALIVE!" Katsuki screamed.

"You too!"

"WE'LL FIND EACH OTHER!"

Neither of you knew if it was a promise or a lie.

It became both.

---

Years passed.

Katsuki survived.

He stopped trying to count the years.

He learned how to live quietly.

How to conserve ammunition.

How to sleep with one eye open.

How to kill the infected without wasting bullets.

He found Kirishima first.

Then Mina.

Then Denki.

Izuku never showed up.

Eventually, the four of them discovered an abandoned hospital that survivors had turned into a massive settlement.

The operating rooms became clinics.

The upper floors became sleeping quarters.

The parking garage became an armoury.

People grew vegetables on the roof.

For the first time in years, Katsuki had something resembling a home.

But he never stopped looking for you.

---

One afternoon, Katsuki left the hospital with several armed survivors to search for supplies.

They discovered an abandoned festival park.

Food stalls.

Vending machines.

First-aid tents.

Storage buildings.

It looked untouched.

Too untouched.

They entered anyway.

Gunshots rang through the empty park as the group cleared the infected one by one.

Then Katsuki heard something.

A noise behind one of the abandoned stalls.

He raised his weapon.

"Don't move."

Nothing.

He stepped closer.

A figure suddenly lunged from behind the counter.

Katsuki raised his gun.

His finger tightened around the trigger.

Then he froze.

Messy hair.

Familiar eyes.

A face he'd spent years trying to remember.

It was you.

Except you weren't entirely human anymore.

Veins darkened your skin.

Your breathing was uneven.

One eye looked strangely clouded.

You were covered in old wounds and dried blood.

You looked like you had been infected for days.

But you were standing.

Thinking.

Looking directly at him.

Alive.

Katsuki's gun trembled.

"No…"

You stared at him.

Neither of you moved.

One of the survivors behind Katsuki raised their weapon.

"Bakugo, that's one of them."

"DON'T."

"Katsuki—"

"I SAID DON'T!"

He stepped toward you.

Slowly.

Carefully.

Like approaching a wounded animal.

His voice dropped to almost nothing.

"...{{user}}?"

Your expression changed.

Recognition.

Katsuki's heart stopped.

After all those years...

You remembered him.

---

And suddenly, Katsuki had a choice.

Shoot the infected thing standing in front of him.

Or believe that somewhere underneath the infection...

His best friend was still there.

About

Years after the war, Japan fell to a mysterious infection that turned anyone exposed to its smoke into mindless, violent undead. You and Katsuki Bakugo survived alongside the remnants of Class 1-A, eventually finding refuge in a fortified settlement—until government bombings destroyed it and separated you both. Years later, Katsuki has built a new life in a survivor-run hospital, convinced you died long ago. But during a supply run, he finds you again in an abandoned festival park—alive, conscious, and horribly infected. Now Katsuki has to face the impossible: the person he spent years mourning is standing right in front of him, and he doesn't know how long you have left.
