As of the moment, Tsuna cannot open these due to not having his Vongola Ring.
--1. Natsu, Leone di Cieli Version Vongola, is the most recent of Tsuna's boxes and was created solely for the reason of being passed down to his future self if everything went according to plan. A sky lion cub with the Sky attribute, Natsu is capable of releasing a roar which can petrify others and whose mane can absorb in other flames in a defensive manner. It is unique, however, in that it can transform into two other pieces of equipment (a trait known as Cambio Forma). The first of these is a defensive item, a long black cloak which can neutralize attacks. The second is a metal gauntlet which greatly approves his offensive attack to the point of being one of his most powerful attacks. While Tsuna is familiar with Natsu (being the one to request this box and the others be specially made), he's never truly used it in a battle before since it wasn't meant for the 'him' of this time.
--2. Isabella, Tigre Tempesta, is a tiger cub weapon with the Storm attribute who can cover its tail in flames. One of Tsuna's most physically powerful boxes, its flame can seem like a drill and pierce through objects.
--3. Hanako, 花子, Giaguaro di Pioggia, a jaguar cub with the attribute of Rain. Its most notable aspect are the flames that cover its paws which seem to settle water and allow it (and one other) to walk across it. When it digs its claws into others, the Tranquil effect of rain slips into them to weaken DWFlames and slow the general individual down.
--4. Rikuto, 陸斗, Puma del Sereno, a cougar cub with the Sun attribute whose fur radiates flames. Due to being mixed with Tsuna's Sky flames, that also mingles around the area of its head and throat. When curled up against someone, it paralyzes them (Sky) even as their wounds heal and exhaustion fades (Sun).
--5. Ermete, Ghepardo Elettro, a cheetah cub with the Lightning attribute. The most high strung of Tsuna's box cats, this cub spends more time running away from its enemies than fighting them. However, as it runs, it gathers power which erupts in short bursts that gathers nearby materials in a defensive shield hardened by the Lightning attribute. They quickly fall apart after being hit, however, and Ermete can only do so many due to low stamina.
--6. Yuki, 雪, Leopardo di Nebbia, is a leopard cub with the Mist attribute. It's often easy to lose sight of this one even if it's in plain sight because of its Mist Flames, which seem to lay within its spots. It radiates a constant but subtle illusion, throwing people's center of balance off and making them feel nauseous. It doesn't seem to listen to Tsuna very much but its illusions can be calmed at his touch.
