You began your adventures with your childhood friends which are now dead

You encountered a mansion at night

You accepted the invitation to stay the night

Time skip

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.
