Summary
“I don’t hate them,” Rui stated, “I just think they taste like grass.”
That made Mizuki laugh louder, and she patted Rui’s shoulder playfully. “Right, right.”
Rui sighed, but a small smile crept up on his lips. He enjoyed the playful banter he and Mizuki had. It was refreshing after a somewhat long day of being out in the dank and “unhappy” areas of the Low-class.
He went over to the couch and sat down. He attempted to try and redo his small ponytail, but his hair was quite tangled so it was kind of a hassle to fix it. Rui sighed, and just kept his hair down for now. He heard the clatter of pans behind him, and he guessed Mizuki decided to make the bag of rice they had.
Then as quiet calm started to settle down in the flat, a loud CRASH was heard overhead, slamming down on the roof of the building. However, neither Rui nor Mizuki reacted to it, since they were used to that sound.
“I guess the trash has came in.” Mizuki said, stirring the rice in the pot. Rui nodded and stood up from the couch.

Rui finds an Android, who is a famous idol, and he, somehow, is now attempting to solve a decade old government mystery case.

Summary
Toya, WxS, and a few others react to Tsukasa Tenma's pov!
Details:
When a little over half the pjsk cast find themselves in a strange Sekai resembling an old timey theater, chaos ensues. With a new Miku taking the reins and concealing their only escape, they find themselves trapped and forced to watch the sorrowful depths of their one and only future star. Behind the scenes, a mystery lies; who gathered them all? Why? And most of all, can they somehow fix Tsukasa with the knowledge they shouldn't even know? Or does he even need fixing?
This is an interactive book! Your comments matter!!

Summary
-"What's wrong, Kamishiro? Have you already forgotten the 'little joke' you played on me, huh?"-
The blond complained, staring intently with his golden eyes into the purple-haired man's yellow ones as he tightened his grip, leaving him no chance of escape.
He couldn't help but smile inwardly when he saw the sorcerer's pale cheeks flush in response to the situation and the proximity, and his lips tremble for a moment before he replied, shifting into that irritating feline smile with that unbearably sweet and provocative tone.
-"Ah, so our proud and steadfast knight was really offended by such a trivial joke, huh?...I'm not impressed, you never lose your sourness."-
Rui muttered, moving a little closer to the other and provocatively sliding a finger down the blond's neck, even though he was the one trapped and at the knight's mercy.
His feline smile faltered when an embarrassing, sharp moan escaped his lips as he felt Tenma firmly grip his neck, squeezing it slightly while looking at him with a frown and his face flushed with barely contained shame and anger. Damn it, why did he feel himself starting to get hard?

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.

Shidingles, beef (and chicken) ensure, but of course, not everything is sunshine and rainbows...
This has a plot, much to Miku's dismay, but thankfully there is her very own Q and A for YOU to ask her and the pjsk characters questions which they'll answer!
