Summary
Rui lived in a place that he couldn’t quite describe. White or gray walls, rooms filled with medical supplies and testing equipment.. Alongside that, several psychologists, doctors, and scientists filled every room. At least, every room except for at night. At night, they all got to go home.
All of them except the subjects. The subjects never got to leave.

Summary
Loneliness isn’t something you cope with easily. It’s something that never leaves you. Of course, you can fill the void of nothingness with friends here and there, perhaps even a relationship, but you can never run from solitude.
Rui Kamishiro was lucky enough to be a part of the group of people who find friends and even a lover. Not many people who suffer from loneliness are able to do so. For the most part, he believed he finally found where he belonged.
..
So why exactly was he moping around in his room..?

Rui feels something familiar, almost as if he was lonely, despite having all the friends he could ever need

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
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.
