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.

Summary
If you asked him, he couldn’t quite give you a clear answer. Did he come to the ceremony to get enough money to help move his mother to a safer part of town? Maybe he decided to go to escape the townspeople just for a night? Or perhaps, he just came here simply out of curiosity.
Or
Rui decides to go to the ceremony being held by the Rose family, only to cross paths with Tsukasa, the cursed prince.

Summary
Have you ever wanted to play the hit mobile rhythm game Hatsune Miku: Colorful Stage! inside your favorite AO3 fic? No? Well for some reason I wanted to see if it was possible, so this fic exists now. This took about 7 hours to write the code for. I still don't know why I did this. But it's pretty funny!
Device Requirements:
- Any modern browser (Firefox recommended, Chrome & co. is a bit buggy)
- A big enough screen to render the virtual "tablet" (you might need to rotate your phone)
- The ability to "click" and "hover" (basically a mouse/touchpad/touchscreen)Bookmarked by polygonee (Ponii)

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 watched as the man glanced around the shop. He cleared his throat and spoke when it seemed like the man was facing him. “Sorry, but we’re closed.”
“Really? The strangest thing then, your sign reads ‘open’.” The man responded. Tsukasa let Pochi jump out of his arms as the man approached the counter. “This is that little shop that fixes everything, right?”
“Well, yes, but—”
“Perfect.” The man took the hood of his cloak off, revealing messy purple hair with two strands of blue and a pair of yellow eyes. “I happen to have something I need fixed.”
After giving his name away, Tsukasa's forgotten by everyone he's ever known. That is until one day he meets someone that can't seem to forget him, someone that just might have the key to fixing that.

The war is going nowhere.
With the two enemy kingdoms facing a stalemate, there's no chance to initiate battle. Which means everyone is stuck in the same place, unable to do anything.

Summary
Only a fool would believe in ghost stories. Only a fool would willingly go to the damned ruins of a fortress that rests above the clouds, drowned in snow and ice. The stories of that place are myths, designed to scare people away and keep them safe.
Myths have their roots in reality. Tsukasa is a fool.
