After the Great Sage resets the world, Yogiri and Tomochika are forced into Van's new game in order to obtain the Philosopher's Stones—their only lead for getting home now that Luu is gone. Although Yogiri can't use his power without breaking the game, Tomochika's combat prowess and the old friends they made along the way may be just enough to get them to the final boss. Everyone's in for a surprise, however, when the Philosopher's Stones start disappearing from the game...including the stones the party's collected so far! To make matters worse, the Great Sage finally makes a move against Yogiri while they're coming to grips with the missing stones!
