You began your adventures with your childhood friends

You encountered a mansion at night

​

You accepted the invitation to stay the night

Time passes

As you walk through the mansion's grounds, the silhouettes of people standing in the sky at night catches your attention

You see a red moon.... Below are the silhouettes of a girl with pink hair and a weapon, a girl with black hair and a katana, a guy in armor with a spear, and a human beast, and a guy with green hair.
