There are a few days left before Christmas, and Mito still doesn't have the money to get a nice gift for his girlfriend. So he goes to the Master who offers him help but in exchange proposes a very entertaining game to the boy, well at least very entertaining for the Master but quite painful for poor Mito. Unfortunately, Mito can't escape it if he doesn't want to show up empty-handed to his girlfriend. So Mito must grit his teeth and face the harsh reality, even if it is so very difficult and tempting for him to give up.
