Gatto Tempesta ver. Vongola, nicknamed as Uri, is a Storm-attribute Animal-type Box Weapon. It is the exclusive Vongola Box Weapon for Hayato Gokudera.


The Gatto Tempesta ver. Vongola was created by remodeling a Gatto Tempesta with the Vongola's latest technology. A part of the Sistema C.A.I., through Cambio Forma, it changes into a weapon similar to the archery-style weapon employed by the first generation Storm Guardian. The red arrow it releases boasts astonishing destructive power through its Storm Flame.

Uri has a mischievous nature and is constantly antagonizing Gokudera every chance it gets. After it was upgraded into a Vongola Box, the most distinct changes were an increase in size and the addition of a crest in its forehead and Storm Flames on its paws.

  • Uri once attacked Natsu for being frightened in camp before the Future Arc final; he also scratched Tsuna's face in haste to get out of the hospital room Gokudera and Yamamoto were at.
