The player is introduced to a class and well.... friends but then you know about some girl in the class that has "Vanished". I am sure by now you probably know where this is going or have atleast heard the story before, nonetheless The player goes out to save her and free everyone from the curse.

Also this will tug at your heart strings for the entirety of the game but i still found it a bittersweet short story and i think you should definitely give it a try. Oh and it also has an amusing amount of deaths and ways to die that i would just do something completely obvious that's going to kill me just to see how he dies, its funny really lol.
