Uri is a Box Weapon that Future Gokudera left behind. It was kept in one of the Sistema C.A.I.'s Storm Boxes. It has a problematic temperament and its performance as a weapon is low and hardly useful. However, by absorbing Sun Flames, it matures into an adult Storm Leopard with great physical ability, though it's temperament remains the same.
Gokudera Hayato, though he complains about it frequently, loves Uri dearly and comes to see it as a valuble ally. Uri feels the same way about Gokudera and is very protective of him in both kitten and adult form, like a mother cat guarding its kittens.
- Its name, "Uri," means "gourd" or "melon" in the Japanese language.
- Uri's voice actress, Rie Tanaka, also voices Bianchi and Hibird.
