Tsukasa tenma is a star.
At least that's what he’s always wanted to be.
And for a little while that's exactly what he was.It was everything he could ever wish for.
Of course there was his best friend rui, and nene and emu too!
Together they were wonderlands x showtime, a well known show troupe that would go around performing shows for people of all ages.
Unfortunately all good things must come to an end eventually.will add tags/warnings as i write it.

Summary
With his whisk inside of his shaky grip, Tsukasa's body shuddered in enragement when he saw the stray pudding drops on the floor. “You!”
Following the trails of the drops, there stood a six feet tall man with a small spoon held by his metal clawed hand. His pale golden eyes stared down at him with a neutral expression on his face, almost innocent with the way he blinked slowly and the near ends of his mouth were cladded in pudding. That little pudding ravager! “Me?”
Tsukasa stood there as Rui, the mysterious being he came to know as a dessert robber, took another gallop of pudding inside his spoon and ate it while watching him. Tsukasa's left eye twitched.
Maybe he should've listened to Minori when she suggested using a crucifix, holy water or an ouija board.

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..?

The sequel to Μέδουσα - Médausa no one expected
About two years after Rui's first arrival to the drylands, life is going swell for him. He's happily living with Tsukasa, the love of his life, and Saki, the latter's sister; and even has a job interview ahead of him now that the girl no longer needs 24/7 care!
All's going well, and even better after Tsukasa makes him a proposal he can't refuse, but...Let's say some skeletons have awakened from someone's closet.
Will it be a bad, or a good thing, I wonder..?

Summary
Ever since he was young, Rui watched the people whom he couldn’t connect with. He watched the talks people had – the talks that he thought he would forever be unable to participate in.
They were mundane, yet fascinating. Simple, yet complex. He longed to be able to interact with people, even if he found their conversations uninteresting and meaningless – at least he would have someone to talk to.
However, one topic appeared in everybody’s conversations: love.
