Kojirou

Yamamoto’s swallow. [Manga Debut: Chapter 140 – Anime Debut: Episode 75]

Kojirou has been upgraded after Yamamoto was given the Vongola Box. It can now Cambio Forma and be used to combine with the Shigure Kintoki . This forms a legendary blade that was used by the First Vongola Rain Guardian, the weapon that is said to wipe everything clean, the irregular quadruple blade Asari Ugetsu .The tranquilization of these Flames can be so powerful that the opponent’s flame based attacks appear to be not moving at all, as shown in the rematch of Genkishi/Saru and Yamamoto during the Choice Battle.
