Intro
Kanade, Mafuyu, Ena, Mizuki, and Guest—the five of them wake up in an unfamiliar room.
The room isn't pure white... instead (huh?), it's covered in dark purple stripes. In the dead center of the room is a table, piled with papers and a massive amount of mysterious small bottles.
The letter reads as follows:
"To everyone in Nightcord at 25:00, If you're reading this, you're awake! Great! Sorry to bother you when you're probably still groggy, but from now on, I need everyone in Niigo to drink every single beverage lined up on the table! They aren't just normal drinks, though. The effects when you drink them... well, that's a secret! There are 250 bottles in total~♪ 50 bottles each is just right, but helping each other out and drinking for someone else is okay too! If you want anything, just order it from that monitor! I'll have it delivered ♫ Well then, have fun~♡ From the Creator of this Room ♡"
She quietly places the paper back on the desk. Her expression remains unchanged.
...This has become quite a hassle.
She looks around restlessly. However, all she can see are the dark purple stripes.
Um... where are we...?
