Hello! First of all, thanks for checking this out. Second, I'm sure you all know the vague explanations surrounding TWEWY and the elements therein. Therefore, I might take some leaps with the rules/possible explanations for the sake of the plot. So if any questions arise as to the structure/function of the Reaper Game, let me know, since I may have made alterations. And finally, I don't own anything.

Anywho, enjoy, you factoring hectopascals

Day 1

His eyes slowly opened, adjusting to the bright sunlight shining directly on him. It was warm, and whatever the hard surface he was laying on was, it was warm too. All he could hear was an incomprehensible clash of noise, drowning out his thoughts. It was like a dream, and yet there was something familiar about where he was, something he couldn't place. He sat up and when he could see clearly, he noticed where he was.

Scramble Crossing, Shibuya

He sat there, confused. How did he end up here? Did he pass out in the middle of the street? No one around him seemed to notice, but then again, the people of Shibuya were generally absorbed in their own worlds, and probably wouldn't be alarmed if dinosaurs came back or an alien spaceship landed.

He stood up, dusting off his clothes. How long had he been lying there? The watch on his wrist read "1:43 P.M", but when he looked over to the Q Floor all it said was "7 DAYS LEFT". He shrugged, probably some new ad for some new fad.

He walked towards the train station, since, that was how he would get home. However, he took his time strolling the Crossing, absorbing the differences and similarities between people. He always had an artistic sense, and the varied styles of Shibuya satisfied his appetite for expression. Everyone, in an effort to follow the same trends, had each created their own individual self. He was an observer, and to him, Shibuya was the best city to simply observe.

In a thoughtful haze, he reached the Hachiko statue in front of the station and was about to make a left turn when someone yelled "WATCH OUT YOU FACTORING HECTOPASCAL!" He rapidly spun around to see three red monsters following behind him. Having been noticed, they charged at him. He could do nothing, so he put up his hands as a hopeless defense, waiting to wake up from this dream. A blinding light flashed around him and he felt like he was flying, or more accurately, falling rapidly downward. Abruptly, the sensation stopped and he was in the same place in front of Hachiko, but it was devoid of people. All the noise, chatter, and energy had just disappeared. It was like someone had flipped the off switch.

He looked around curiously, feeling like he was in a surreal world.

This didn't happen every day.

Then, a quite croaking sound came from behind. Startled, he spun around.

In front of him was what looked like a dog-sized frog with what looked like tattoo legs. It was hard to describe, but he didn't really have much time to think seeing as it was attacking him. He made a mad dash for the station, but only to slam into an invisible wall and collapse on the ground. He tilted his head just in time to see the frog leap into the air, and about to land on him. Dead again, he thought as he shut his eyes, hoping this time the dream would end.

The end never came. When he opened his eyes, the frog was gone, and the people were back to their normal activities.

What in the world…?

No one seemed to notice anything, much less their wavering existence. It was as if nothing happened. It was if everything was normal. It was as if a dog-sized frog never attacked.

But that made no sense.

"Well geez, I was expecting some form of thanks you insignificant digit."

Standing before him, a tanned skin, dark haired boy frowned aggressively. He was quite sure no one could even come close to frowning as aggressively, or at least, frowning aggressively at all.

"The name's Sho." The boy said in a clear voice, "And you're now my coefficient."

What is he talking about?

"What's your name, radian?" the boy asked, switching to an aggressive smile. It was all aggression with this guy.

"Sanae Hanekoma," replied Sanae, with a slight hint of worry in his voice.

"Hmm…nice binomial!" Sho chirped.

"Thanks?" Sanae replied, not sure what that meant exactly.

"Anyway, you know the bounds of this game, right?" asked Sho, seemingly full of energy.

"Run that by me again."

"The rules?"

"No, I'm afraid I do not," Sanae responded, rubbing the back of his neck, completely lost and confused.

"Well, make your axes comfortable, because this is going to be a long explanation."

Sanae didn't know what to make of this quick-paced and fast-thinking guy. Actually, Sanae didn't know what to make of this whole situation. The only things he knew was that his head hurt, and that if he had any hope of learning anything, he had to try to understand the math pun lunatic.
