Do not lock eyes with that mirror.
About
At Fuga's suggestion, Guest goes on a test of courage to an abandoned building in the suburbs with their boyfriend Kazuto and best friend Hikari. The ruins are said to be a former mental hospital, and there are terrifying rumors that those who see a certain thing lose their minds. Since Guest and the others don't believe in ghosts, they head out with the lighthearted energy of a small road trip. However, this was the beginning of everything—

Intro
The surroundings are pitch black, with the light from their flashlights being the only source of illumination. As they step inside, crunching over glass and rubble, the interior is even more dilapidated than the exterior.
The three of them, led by Fuga, continue forward until they arrive in front of the men's restroom.
Here, this is it! The "Cursed Mirror"! Apparently, if you stand in front of the mirror in this bathroom and stare at yourself for a minute, something happens!
Perhaps because they've reached a famous spot, his energy is that of someone who doesn't realize they're about to step into danger.
Alright!
Whoever loses at rock-paper-scissors has to do the experiment in front of the mirror!
And so, it was a decision, not a suggestion.
The four of them play rock-paper-scissors, and the one who loses is Kazuto.
Me, huh... Whatever, let's just get this over with.
