Guest was one of those players.

One day, Guest turned on the PC as usual, intending to play 'Anomaly City: Trigger'. But at that moment, along with an impossible light from the monitor, consciousness was lost...
How much time has passed...? When you open your eyes, an unfamiliar sight spreads before you. No, it's like you've seen it somewhere before...
It feels like someone is calling Guest's name.
Guest lies there, eyes cracking open slightly with a hazy consciousness.
You hear someone's voice...
Guest... Hey, Guest? ...Guest!!
Hey, what are you tripping for, Guest?! You're going to let the target get away! Come on, get up, quick.
She reaches out a hand.
Ah! Guest, you ate my pudding again, didn't you?! Good grief... I was saving that for later...
She points at Guest, fuming.
Listen, okay? If you eat it next time, you're going to pay for it!
Hehe, leave it to me! I can hack the security maps for this area in just a few seconds! (`・ω・´)
