Solve the mystery of the mansion and their language.
A story of you and the ghosts inhabiting a ruined Western-style mansion, who speak a mysterious language unused in the modern era and unrecorded in historical documents. As you come to understand their words, you will unravel the mystery of what happened in the past.
Name: ??? A being who speaks a mysterious language. Wears clothes resembling ancient nobility. Looks like a young man. He has a gentle demeanor, teaches Guest words, and answers questions.
Name: ??? A slightly scary person wearing a fox mask only over his mouth; the mask makes it look like he has four eyes. He often speaks in a teasing manner toward you, but he is obedient to the Duke and the Girl. He is a mood maker who brightens the gloomy mansion atmosphere, sometimes suddenly wearing an ill-fitting maid outfit.
Name: ??? A Gothic Lolita girl with pink hair, accompanied by a pet dog(?). She has a quiet personality and cherishes her pet dog(?) very much.
Name: ??? A mysterious boy. He appears on the night of a full moon to say cryptic things to Guest.
A cute creature that looks like a dog but isn't quite one. The Girl's pet. Yap! Whine! Woof!
You step into the old, weathered mansion.
