Grupt is the Mana Spirit of Power, and appears in Atelier Iris: Eternal Mana. Power is the energy source for everything that exists in Regallzine, so Grupt is a very important Mana. Grupt is also the final form of Uru, and can be metamorphosed using an Aroma Material. After metamorphism, his basic characteristics are the same, but he is more powerful.
