Vongola Rain Box Animals

In the future arc a new power is introduced known as box weapons. Box Weapons are powered by a specific flame attribute. When properly charged the box opens to release "something" to make the user stronger in battle. For example, boxes may contain weapons such as swords or guns or animals such as dogs, lions, dolphins, hedgehogs, etc. Each guardian gets a few weapons from their future self and upon capturing the Melone Base they are given weapons which inherit the powers of the first generation Vongola Family. They take these weapons back to the past and they become combined into the new Vongola Gear.

Kojirou is reconstructed Rain-Element swallow made specifically for Yamamoto's use. It was made using the Vongola Family's newest technology. Its basic abilities are just like other "normal" Rain swallows that are apparently mass produced at some point, but it can also unite with Yamamoto's Sigure Kintoki in Cambio Forma, and it changes its form to become a long sword similar to that of the first Vongola Rain Guardian. Yamamoto was the one who named it Kojirou. This name supposedly came from the name of a sword master who was very famous for 'Tsubame-gaesi' After the original Vongola rings were destroyed Kojirou became part of the new Vongola Gear, Necklace of the Rain. Nothing really since Kojirou already united with Shigure Kintoki in Cambio Forma, now though Kojirou is Yamamoto's right blade since he moved to a two blade style rather than the four blade style of Asari Ugetsu.

Jirou is a reconstructed Rain-Element Akita-Inu made specifically for Yamamoto's use. He is made using the Vongola Family's newest technology as well. He's still a young dog, so his job is mainly just carrying Yamamoto's 3 small swords in his Cambio Forma. This name supposedly came from Karahutoinu Jiro, very famous Artctic sled dog. After the original Vongola rings were destroyed Jirou became part of the new Vongola Gear, Necklace of the Rain. In that form Jirou becomes part of Yamamoto's left blade. Jirou and Kojirou actually reside in the same box which is unique compared to other box weapons. Among the Vongola Boxes Yamamoto's is the only one with two different types of animals.
