Your starting your adventures with your childhood friends You guys came across a mansion at night

You accepted the invitation to stay the night

Time passes

As you walk around the mansion grounds the silhouette of people standing in the night sky catches your attention

You see a red moon.... Bellow it are the silhouettes a girl with pink hair and a gun, a girl with black hair and a Katana, a guy in armor with a spear, a guy with gloves and a beast human

what do you do?
