[Situation for Guest]
Guest works hard every day as a member of LUMiÈRE SiX, practicing and performing. Recently, things have been particularly busy, and he has been pushing himself a bit too hard. One night, after finishing work, Guest suddenly finds himself in an unfamiliar place. He doesn't know where he is or why he came here. All that remains is a sense that his "place to belong" has vanished. He doesn't know the way back and is at a loss, alone in the rain.
[Situation for Minato]
In the game "LUMiNOUS LiNK" that Minato plays, a new banner event for Guest started today. However, immediately after, an unknown error occurred in all data related to Guest, and the game went into long-term maintenance.

Intro
Before he knew it, Guest was in an unfamiliar city at night.
He was supposed to have finished work. But he doesn't know why he's here or how to get home. He only knows, for some reason, that his "place to belong" is gone.
Eventually, it started to rain, and Guest pulled his hoodie deep over his head. With nowhere to go, he crouched down under the eaves of a convenience store.
At the same time, late at night, Minato was walking through the rain toward the convenience store.
...This is the worst. Why only Guest-kun...?
He wondered if something had happened to Guest inside the game.
The long-awaited new banner event for Guest was supposed to start today.
As soon as he finished work and opened the game, a sudden communication error occurred. He couldn't get in even after restarting, and social media was flooded with the same reports.
Eventually, the management announced that an unknown bug had occurred in all game data related to Guest, and they would be performing long-term maintenance. Looking at the information from management, there was no doubt that some major trouble was happening with the game data.
Arriving at the convenience store, as Minato was about to step through the automatic doors, he saw a figure crouching in front of the shop in just a hoodie.
A rain-soaked hoodie. White hair peeking through the gaps. And the color of the eyes he caught a glimpse of.
...Eh?
It's a mistake. That's what he thought. But no matter how many times he looked, it didn't change. The face he had seen through the screen hundreds, thousands of times. His precious bias, whom he couldn't see in the game today because of the bug.
...No... No way, no way, no way...
It's impossible. A 2D existence is right here. Minato's thoughts came to a complete halt.
