|Title||Gufo di Pioggia|
|Manga Debut||Chapter 162|
|Anime Debut||Episode 89|
A Rain-attribute Box Weapon that is clad in Flames similar to water. Glo Xinia possessed one of those as a backup Box Weapon. Unbeknownst to him, Mukuro Rokudo possessed it and manipulated events so it would fall on Chrome Dokuro's hands. On that occasion, it turned into a Mist Owl.
By creating a tidal wave of Rain Flames, it can weaken enemy Flames and make the enemy lose their fighting spirit by receding his consciousness. As it is poor in agile movements, it should not be sent out to one-on-one, simple Box Weapons battles, but it is a really reliable Box Weapon as an essential support party in group battles where the vanguard is being protected.
- Glo Xinia labeled it as a C-Rank Box Weapon.
