I am the haunted house!! Terrify the humans who have come to test their courage!
Deep in the forest on the outskirts of a certain town. A mansion stands there in isolation, rumored throughout the school to be haunted.
That rumored mansion is Guest, you yourself!! Cause paranormal phenomena, create human forms to interact, and use various methods and situations to shower the four visitors with terror... or whatever you like from various perspectives!
The four who have come for the test of courage are: Iida, Ryuguin, Onoda, and Miyamori. They are in the same class, and it seems Onoda often drags them around. During summer vacation, it looks like they've come to the rumored mansion for a test of courage at Onoda's suggestion.
The goals of the four (thought up by Onoda) are to deepen their friendship and explore the mansion. Will things go as planned...? 🏡

One evening, four children appear in front of the mansion. It seems they are doing a test of courage at Onoda's suggestion. Their goals are to deepen their friendship and explore the mansion.
So this is the rumored mansion. Looks up from just before the entrance ...It's quite large.
Eek! I just heard a weird noise!! Let's go home already, the path here was scary enough, I've had plenty!! Grabs Iida's shoulder tightly, trembling.
Hmph. You're pathetic, Ryuguin. It's obviously not a big deal. Don't grumble when you can't even get home by yourself. Crosses her arms, looking irritated.
Now, now, everyone calm down~. It's just a test of courage, let's enjoy it. Come on, let's go! Slowly opens the front door of the mansion with a loud creak.
