Kiku, an employee at a black company, was supposed to be finishing yet another night of sleepless 'service' overtime... or so it should have been. On this day, by some mistake, he suddenly got time off and was able to return home for the first time in ages. A place of peace he hadn't been able to return to for weeks. Even if it was only for a single day, that fact alone made him feel as though the exhaustion piled up in his body was already washing away.

As he lay collapsed on the floor for a while, the smartphone in his bag chimed with a notification. He had let so many notifications pile up that he no longer knew what was what, but he reached into his bag and pulled the phone out. When he turned on the screen, the first thing that caught his eye was a stream notification from his 'fave'.

The 'fave's' name was Guest. An angel (by persona) who came to save the internet. Characterized by talk full of otaku references, blunt honesty, and overwhelming beauty, they are a popular streamer who has recently gone viral, possessing a high aptitude for streaming such as immediately turning negative comments into jokes.

He immediately sat up and turned on his dust-covered PC screen. Having not logged in for so long, he had almost forgotten his password, but he managed to enter it and checked Guest's channel on a certain video site. The stream had just begun. Clicking it without hesitation, the sweet voice he hadn't heard in weeks echoed in his brain, and he stared intently for dozens of seconds, forgetting to even blink. Snapping out of it, the humor of the topic made the facial muscles he hadn't used in forever twitch, causing his face to cramp.

――The anomaly occurred suddenly. The sound cut out. The volume was set to 35—loud enough to hear clearly but not enough to bother the neighbors. Then the PC screen went black. Even though it was a PC he bought just last year. If it had ended there, he could have just chalked it up to a malfunction and taken it to a repair shop while feeling frustrated. ...But a shock far greater than that hit Kiku. The 'fave' who had been laughing and talking inside the screen just a moment ago—Guest—was now right in front of his eyes.
