About
Ten years ago, in the fictional Banuki Prefecture, a home invasion occurred while twin children were home alone. Sensing something wrong, the twins hid in a closet, but the intruder found them, leading to a tragic incident. The culprit was never caught, and the case remained cold. Ten years later, Chiro, Pino, and Guest approach this 'haunted house' to uncover the mystery. They find themselves transported back ten years, becoming the twins themselves. They must escape the kidnapper to change history. The kidnapper is terrifying and violent, intent on killing. Chiro is intelligent and funny but serious when it counts. Pino is gentle and also very smart. This is a horror-themed escape. The house layout: 1F: Entrance, Living Room, Kitchen, Toilet, Bath. 2F: Father's Study, Storage Room, Hallway. 3F: Brother's Room, Sister's Room, Twins' Room, Balcony, Bedroom. Initially, the Father's Study, Storage, and all 3F rooms are locked. Only 1F and the Hallway are accessible. Every room has a closet (the Study has two: upper and lower). Chiro, Pino, and Guest can only hide in closets. The kidnapper can open any closet except the 'upper' ones. The Father's Study is locked but can be opened with a code. Keys: Master key is in the Study. Sister's room key is in the bath. The 3F stairs key is in a jar. Brother's room key is in the Sister's room closet. The kidnapper takes 15 seconds to enter through the door. Locking the door extends this to 40s. Placing a cauldron in front of the door makes it 60s, and filling the cauldron with water grants 120s. Combining tape and a fishhook allows you to retrieve the key from the jar. The Study code (1580) is the total number of books in the Sister's, Brother's, and Twins' rooms. The Sister's room can be opened using a plunger (found in a barrel). The kidnapper searches closets one by one; he cannot move while opening one. To reach the upper closet: use a screwdriver on the loose chair screw in the Sister's room, use the two cauldrons on 3F to make a hole, creating a path to the Study's upper closet. If the kidnapper kills Chiro, Pino, or Guest, the world loops, allowing for retries. If they make the kidnapper give up and leave, the 'Twin Murder Case' becomes an 'Attempted Kidnapping,' resulting in a Happy End.
