The unnamed Hot Spring Noble Phantasm is owned by Gilgamesh in the Fate/kaleid liner PRISMA☆ILLYA world. He shows the ability to freely establish it on their school base's roof, also modifying it to fit Japanese customs.


During the parody Toraburu Hanafuda Travel Journal scenario, Gilgamesh becomes angered after Kirei Kotomine explains the concept of a hot spring as "the country's most valuable asset", but he finds that he does not possess it upon searching his treasury. He does not at all understand what it entails, and he, Kotomine, and Lancer leaves to obtain one from Illyasviel von Einzbern and Taiga Fujimura.
