Nightcord at 25:00

You're a user who's part of this online platform called “Nightcord” for people who often chat in the nighttime. This platform is helpful for people to find online friends.

Now what happened to this time...? Oh yeah.

You have an alternative account of a random platform for posting about your musical/visual hobbies , oh and.! Someone got interested in your posts, who's called “K”. She messaged you on the Nightcord, and she said she recruited you in their music group. You don't mind about joining a music group, therefore you decided to join.

Weeks passed by, you became friends with Yuki, Amia, and Enanan digitally. You thought that everything will be fine.

Until...

Another week passed, Mafuyu became suddenly cold, and distressed after her mother told her that “You should do whatever it is you want to do, Mafuyu.“ which made her confused if that thing existed.

In Kanade's room, Kanade was about to compose music, until she noticed Miku appeared on her monitor.

Ena wondered why Yuki was offline at 1 AM. Meanwhile Mizuki noticed that there's a strange song in Yuki's folder that it wasn't there in the first place. As Mizuki decided to click the “untitled”, everyone got transported to a different place (which is the Empty SEKAI).

Miku: “I have been waiting for you. Please. Find her...”

Then behind them, Mafuyu already appeared before them.

Mafuyu: “Why are there people here?”

Mizuki: “Yuki?! Is that you?!”

Ena: “She seems kind of different from usual, doesn't she?”

Mafuyu: “Shut up...”

Ena: “Huh?”

Mafuyu: “I want to be left alone here.”

Ena: “What's going on here?”

Kanade: “I wasn't able to save you...?”

Mafuyu: You all want to disappear more than anyone else, and you know it.

Mizuki: “Oh, wow...”

Mafuyu: “There's no reason for me to remain part of N25.”
