Even In A World Like This by Kobilyee

Summary
Living in a corrupted, cyber-esque world wasn’t easy. Tsukasa Tenma could tell you that much. It was more like the proper definition of Hell if he wanted to be entirely honest.
There were two versions of a world humanity lived in. Everyone knew of them.
The first version was your average green, plant-filled world. People could happily exist there without a care. Animals ran around and of course, humanity still existed. Only regular buildings and homes, nothing that would cause the world to collapse. It was the same world you would see if you went outside right now. That was the real world.
The second version was the complete opposite. It wasn’t anything like that. It was an entire computer-generated world that trapped humans inside filled with corruption and technology. It was filled with purples and blues, cyberpunk lights and notions everywhere. It felt right out of a video game except it was as if these people were trapped within the video game.

The star smiled with success, pulling that part of Vulcan’s shirt down. He stands up pridefully before making his way out of the alley. He heard some shuffling, but chose to ignore it… at least he tried to ignore it.
It was hard to ignore when the shuffling came from a supervillain who almost in an instant got to his feet, grabbed you and tossed you upside down, holding you in the air using his robotic arms. Tsukasa screamed out of fear.
This was it. He was going to die. He was going to die by the hands of his favorite supervillain.
★・・・・・・★
Tsukasa Tenma lives in a world where people are born with superpowers.. Because of that, many supervillains and superheroes exist.. Just what happens when you have a healing power and also end up in an alley way with your favorite supervillain who was injured..?

Summary
Rui struggles to control his emotions. When he’s angry, sad, or in any kind of bad mood, they’re extreme. Something tells him something he doesn’t like, and it’s almost as if a volcano erupted, completely destroying the person in front of him as he looks for the meanest thing he can say and drops it out of his mouth like a splash of lava without thinking about it. When he says he’ll try to do better, he tries and utterly fails. He can’t control his emotions, and it hurts. It’s like he can’t think properly and it all just spills out like word vomit. It didn’t help that when he would get angry and he’d walk away – just like people used to tell him to do – the latter tries to keep him there and tells him he’s a pussy for running.
Even though they told him to run, to prevent further arguments, prior.

A Foolish Sorcerer by Kobilyee

Summary
Fighting was normal for the two of them. A continuous battle between one another where it was never stated how to go. Sometimes Kamishiro would win, other times Tenma would. It was never clear who was better than the latter, but nonetheless they never stopped fighting.
People within the kingdom’s quarters would often rumor the two were friends and only fought out of mere entertainment, but it was clear one wanted to get some blood on his hands. Rui never wished to hurt people, it was only inevitable that he did due to a longing curse he had. Tsukasa, however, was the opposite, ready to shed that crimson color whenever possible. If killing that wretched sorcerer would be the last thing he did, he would blindly accept it.

Summary
Tsukasa sensed a strange energy emanating from the man, staring intently into his yellow eyes, somewhat lost in thought. However, this moment was broken when the other man looked at him. "I've never seen you around here, I saw you talking to Miyake, so I guess you two know each other." the purple-haired man said, opening his soda and taking a sip.
"Ah.. Uh.. I don't usually come here at this hour, I was just taking a walk–"
"2 AM?" The taller man chuckled. "I see..."
'What kind of expression is that?!'
"Excuse me?" The blond makes a confused face.
The purple-haired man's gaze grows heavier as he looks him up and down, making Tsukasa feel confused and strange.
“Well, I should introduce myself.. I’m Rui Kamishiro, you can just call me Rui! I don’t mind honorifics!” The man nods with a brazen and strangely suspicious smile.
"Tsukasa Tenma, you can just use Tsukasa..." the blond boy looked away, trying not to pay attention to the heavy feeling those yellow eyes were conveying to him.

Rui is a vampire hunter, Tsukasa is a vampire.
They are idiots.
