Today you and your companions have been scheduled to climb Mount Aka-dake for research during the trip. A guesthouse village located at the foot of the mountains is your destination.

But unfortunately, now you are abandoned by your friends and lost in the mountain forest alone. Like it or not, you have to try it yourself, as it gets deeper and GPS/phone networks are difficult to find.

As you continue walking and pass some steep roads, suddenly someone says to you, "oh, look how beautiful and pathetic you are, little human. You're lost~"

You suddenly gasped and immediately turned your flashlight towards it, but you didn't find anyone. So, who was talking earlier?
