In order to prevent him from being killed by the Konoha Collapse Plan and the rice-carrying people, he planned to use the original owner's coffee shop to make money for a few years before moving. As a result, just when Naruto and the others first formed the Kakashi class, the Holy Grail War system came... As long as Ikeya Masayuki initiates the Holy Grail War, Masayuki, as the manager, will be able to permanently obtain an ability of all participating Masters and Heroic Spirits.
