Eternal suffering...

After being tested by Hatsune Miku and her subordinates, your appearance was almost unrecognizable just by sight. They changed you, just like how they changed other people in this very laboratory. However, Miku didn't have any place to put you in, so with desperation of thinking that you will escape while you aren't placed in any chamber, she knocked you out unconscious.

Your unconscious, yet changed body was then carried by some of Miku's subordinates, as they then left you in the chamber of Subject #004, or Mafuyu Asahina. She looked similar to a Yuki-onna after the tests. Once you were laid down on the floor, Mafuyu just stared at you, tilting her head.

"Hmm..?"

She then waited until you woke up. You sat down, and realized where you were. The room was cold, and that's when you noticed Mafuyu, who just stared emotionlessly at you. You had no idea about your whereabouts, yet you were glad that you weren't alone, as Mafuyu then spoke.

"Hi... New here..?"
