One day, in search for a thrilling mystery as well as easy money, they take several donation boxes and fabricate a curse to scare everyone: “Ohone-sama’s curse”. After scrawling 骨 (bone) all over the chalkboards and spreading rumors of the curse, the donation boxes are quickly filled and the curse becomes a major legend of the school. Of course, only Tomohiro and his friends knew the curse was fake. It wasn’t possible for anything to happen.
