My System & My Academy of Superpowers

A five story building, a total of five floors including the ground floor, and six if we include the rooftop. Coming out of the main plaza will lead you to open ground. 

After passing through the open ground of a few meters, you will be out of the building's area. Ahead stands a big gate which reads: Students' Dormitory. 

Right now, in front of the gate were standing tens of students with anxious, scared, worried expressions on their faces. 

"Uh… man, I don't feel right," Naomi heard a guy talking to his friend behind her, "Damn… I am feeling sick," they were talking in Japanese so Devon and Gwen were clueless. 

"Are you alright? What's wrong?" Naomi turned around to see two guys talking with each other.

One of them had his arm crossed against his stomach, bent down with a pale face. 

"I- I- I can't- I feel--" little disgusted screams broke out in the crowd when that guy threw up.

He didn't stop there, he continued throwing up some green liquid. Everyone moved away from him except his friend who stood behind him. 

The vomiting guy's body started trembling, his body quivered. His body parts twisted in strange angles. It didn't take Naomi another second to guess what was happening.

"Hey Devon... " she spoke, "Won't that guy turn into a zombie now?"

"He will…. Wait! He will!" he came to a realization that they have a living zombie between them who can infect them.

"Naomi, ask that guy to move!"

"Oey! Move away!" but she was late.

That guy lifted his body and threw it over his friend standing beside him. His friend screamed painfully while the zombie devoured him.

"Devon!" he heard Rigid calling him. They understood each others' gestures.

"Two of them. At once!" Devon moved towards the newly turned zombie. 

From the corner, one Japanese guy came to end the zombies.

'Looks like people know what happens if a zombie bites a human.' Devon though.

He disappeared inside the ground, Rigid doubled his muscles. One Japanese guy stopped in between, closed his eyes, and started muttering something.

Suddenly, vines appeared from the ground and grabbed both zombies in the air. 

"Aim for the head. No second chances. Use your superhuman strength!" Rigid shouted. 

Rigid took a step forward and jumped in the air. The muscles of his arms started sprouting out. 

Devon erupted out of the ground with his blood-red eyes. They both, at the same time, punched the two zombies held in front of them.

Blood sprouted everywhere on the ground, their faces. The next second, those two bodies went away flying till they hit the border wall. 

Blood spattered everywhere when their heads hit against the wall. The vines were torn apart because of two powerful punches. 

"First time, yeah? Or have you--?"

"Nah, the first time." they bumped their fists, "Your eyes are bright red, calm yourself down or I won't be able to control my instincts anymore." Rigid whispered in Devon's ears.

"Oh. shit. Sorry, dude." Devon quickly ran away from Rigid. 

"You okay?" Gwen asked Devon.

"Yeah, that was nothing."

"We should check who others are infected by the zombies." Naomi came out from the crowd, "Devon, and Rigid, can you please check for bite marks?" she requested.

"Yeah. won't be a problem," Rigid quickly turned away.

"Devon, you take this side, I will go with Rigid," Rosy came forward. Devon nodded. 

Rosy whispered under Devon's ears when they crossed paths, "Rigid is having a problem controlling it, isn't he?" 

"It's my fault-"

"I heard him saying 'use your superhuman strength' so it's alright. Just stay away from him for tonight."

"Sorry." 

"Uhm! Listen, everyone, I want your attention." Everybody suddenly looked in Naomi's direction, "The sight you just saw, you might have understood what it was. I won't go into details and I am sorry for those two boys.

"Just to make sure that doesn't happen again, we will be doing a quick check to see who's infected. We want your cooperation. If we find someone injected, we will have no choice but to ask a teacher to kill him before he turns into a zombie." 

She continued ordering students while Devon and others investigate for bite marks.

'So this is how real-life zombies look like, huh?' it was not hard for him to believe that there were tens of undead creatures standing in front of him are called 'Zombies.'

After all the stuff going on in his life, meeting vampires, knowing some of the vampire secrets, being attacked by strange people, Ryan learned how to accept reality as it is. 

In fact, he was waiting for when zombies will make their debut. He even has a hunch that demons, werewolves, ghouls do exist in this society. 

In front of him was standing a bunch of mindless, dumb, hideous, gruesome, gross-looking creatures. Right now, they were just walking cluelessly around the first floor.

Lights of the hallways were broken only a few were still in the condition to emit light. Ryan stood there unnoticed by the zombies.

On the ground floor, Henry was waiting for Ryan to come out. Students ran out of the building, teachers entered the building but they didn't see Ryan come out of the building.

"Boss, Ryan is still in the building. We haven't seen him coming out of the building."

"Huh? Hah. he's still inside? Did his mates come out?"

"Every student is out of the building only Ryan is not,"

"Haha! Hahahahahaha!" he broke out in an evil laugh, "That's it~!" he hissed, "Come to me, Ryan. you made things easy, I won't have to hunt for you,"

Ainz went down to the fourth floor with a big grin on his face, "Boys, kill every teacher who had entered the building. Quick."

"Understood."

'I never thought you would make things this easy for me, Ryan.' Ainz originally was going to hunt Ryan down with his army as a decoy to lure away all of the wardens, students, and teachers.

But now, Ainz was being helped by Henry and his partner. Henry was considered one of the best assassins available. And then, Ryan stays inside the building. 

'I will corner you alone… then end you miserably..' Ainz thought.
