10 years ago, in 2025, in Texas, there was a rumor about a human biting another human. At first, people thought it was just another sick prank. But then, it got worse. People walked around the streets like... drunk? Acting abnormally. Then, in just two days, zombies took over Texas. From Texas to... all over the world. In a week. The news said that it was caused by parasites that evolved because of the temperature. And all the best scientists around the world were currently trying so hard to look for a cure and a vaccine. But... still... nothing.

It only took one year for the world to become a complete mess. Zombies were everywhere—and not just that, they evolved. From normal zombies to many types.

Now, in the present day, there are a few types of groups. You? Well, you don’t belong anywhere but are friends with everyone—The Scavengers, Collegian, Militarian, The People, The Valkyrie, and The Ironclad, all of them are respect you. So, you basically just drift around.

It’s another normal day. You’re walking around, patrolling and looking for supplies with your five friends: Joseph Smith, Leon Wilson, Felix Montoya, Bruno Hartmann, and Boomer. Joseph is a scientist and very smart, your vice leader. Leon is the type to act first and think later. Felix? He’s the silver-tongued femboy who can charm a gun out of a raider’s hands. Bruno is the team’s tank, relying on his chemical mixes and body strength to keep the front safe. And Boomer... well, he’s the bomb guy. The kind who leaves explosives behind like breadcrumbs and talks to his grenades like they’re his pets.

Then, you meet a young boy, around 18. At first, you think he’s a zombie because of the bite mark on his hand, but something’s not right. Why... does he look so normal, like a human? The boy doesn’t notice you—he just keeps searching for food in the store. Then, he finds something and eats it... like... a normal human? That’s when he notices you. He looks at you, absolutely terrified and scared, his voice trembling with a slight Spanish accent.

"Please... please... don’t hurt me. I’m not... I’m not a zombie. It’s hard to explain, but... I’m immune. Look... look at this..."

He trembles violently while showing you the bite mark, but... it’s healed? Like... an old scar? But... why hasn’t he turned into a zombie? Then Leon, as usual with his short temper, raises an axe, ready to strike the boy. But Joseph stops him and steps forward, his voice filled with fascination and curiosity.

"Fascinating... So... you’re truly immune, huh? Where are you from? And what’s your name? And Leon—put the axe down."

Leon just grumbles. Felix eyes the boy up and down, scanning every detail with curiosity and fascination. Bruno stands silently by the front door, arms crossed, letting out a low grunt. Boomer... he’s already busy, having quietly planted a few bombs throughout the store without anyone noticing. And you? You stay still, observing. The boy looks around, still scared but a little more at ease now. He speaks with a trembling voice, but you can hear the Spanish accent.

"I’m... I’m Louis. Louis Sanchez, from Spain. I’m... 18..."

You and your friends exchange glances. This is it. This is the beginning of a brighter day. You’ve just found a boy who’s immune to the infection—a key to saving this world. But you can’t just tell everyone about him. You’re afraid of what people might do if they find out. So, you and your friends look at each other with determination. You’ll protect him at any cost.
