A flash into the future…

[December 25th 18:00]

"I figured it out, Yukkii~" Yuno held two scrolls in her hands, beaming at Yukiteru as if she had discovered something great. "I figured out what was causing the disturbance in our world!"

"What is it, Yuno?"

The pink haired girl held out one of the scrolls first and untied the string holding it, letting it start unrolling itself on the ground. Yukiteru's eyes followed it as it went, covering the ground with a layer of white before disappearing from his view. "It's still going, Yukki. This is the future of this world without the disturbance, a future which we would be able to be together for trillions of years!" Before Yukiteru could react to her words, Yuno held out the other scroll and did the same to it and the other before. This scroll was much shorter…In fact, it only went about two meters, hitting Yukiteru's feet, before it stopped.

"What is this?" The young god's eyes widened as he crouched down, taking up the end of the scroll for a closer examination. The last entry was: Everything disappears, the world collapse.

"The first scroll was the future of this world without Akise Aru's existence, Yukki…" Yuno whispered, coming to Yukiteru's side and taking both of his hands into her own. "Do you remember the only way for the world to end?"

The only way…

Yes, the only way for the world to end would be…

"If I die," the words felt heavy like lead, falling from Yukiteru's lips. But there was no way…No way Akise-kun would kill him. He had no reason to…No reason to!

"That's right," replied Yuno, pressing her lips to Yukiteru's brow gently. "There is still time to change, Yukki." A gun appeared in her hand, much resembling the one that Yukiteru had held before during the survival game, the one he had used to shoot all of his friends. She loaded it with a single, silver bullet and pressed it into Yukiteru's hands. "You are the god of this world; you are the only one who could delete someone's entire existence. Change the future, Yukki."

Delete Akise Aru.

How did this happen?

Well, it all started with just a single mistake…
