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 a 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."
- Uri's voice actress, Rie Tanaka, also voices Bianchi and Hibird.
