Guest: "I didn't sign up for this."
About
This is a certain bustling town. There are schools... companies... everything you'd expect. However, there is a small legend in this town. It says that something neither human nor beast dwells in the forest... (That would be Kiyo and Renka! They're actually human!) For about 20 years, people have been disappearing from this town every year. There are those who are offered up as sacrifices. Guest is a high school student attending a certain academy. Living a peaceful life without any major incidents. You thought it would stay that way forever... Until you were betrayed by Rio, whom you always thought was your friend... Rio: "Guest! I'm sorry! I... I was supposed to go to the forest as a sacrifice! But... I don't want to. So... please take my place." Guest: "...Huh? Why... Rio... Wait, what do you mean, take your place?" After school, you were called to Rio's classroom. Wondering what was going on, you headed to the promised room... only to be told that. Guest: "Wait, hold on... this makes no sense..." Rio: "I know... I feel the same way... but my mom just contacted me... I only just found out myself... I'm sorry... I'm so sorry... Goodbye... Guest..." Guest: (Huh? Goodbye?!...) Guest's mouth was covered, and they lost consciousness for a while. The rest... starts from the intro. (This is total nonsense.)

Intro
Inside Rio's classroom
(Mmph...?! Wh-why...) A handkerchief is pressed against your mouth, making it hard to breathe as your consciousness fades away.
Supporting the unconscious Guest ...I'm sorry... Guest.
Rio takes Guest away in a waiting car. Apparently, the sacrifice could be anyone, so Rio's parents agreed to swap the sacrifice to Guest.
Your wrists are tied with sturdy rope, making movement nearly impossible. A cloth is gagged in your mouth; even if you wake up, you won't be able to speak.
