Kojirou
Seiyuu / Dub
Summary
Kojirou serves as the Vongola Rain Swallow, a Box Weapon introduced in Chapter 140 of the manga and Episode 75 of the anime. This creature is half of the Vongola Rain Box and is utilized exclusively by Yamamoto. It possesses the unique ability to emit Rain Flames that neutralize an opponent's Dying Will Flame, a power notably demonstrated when it extinguished Nosaru's Flames during their confrontation. Additionally, these Rain Flames function as camouflage, as evidenced when Future Yamamoto used Kojirou to conceal the entrance to the underground Vongola Headquarters. Following Yamamoto's acquisition of the Vongola Box, Kojirou underwent an upgrade that enabled it to perform Cambio Forma. It can now fuse with Yamamoto's Shigure Kintoki to create Asari Ugetsu, a legendary irregular quadruple blade wielded by the First Vongola Rain Guardian. This fusion allows Yamamoto to mimic the First Guardian's style, wielding the long sword alongside three short swords provided by Jirou. The tranquilizing power of these Flames is so potent that it can render flame-based attacks appearing completely stationary, a feat displayed during the rematch between Genkishi/Saru and Yamamoto in the Choice Battle. The Box is an animal-type entity with a Rain attribute, measuring 17cm in size. Constructed using Vongola's latest technology, Kojirou maintains a friendly and sociable personality. While its base skills include rushing, rain shield, downpouring, wave, and pecking, its true potential lies in its transformation capabilities. Yamamoto named the Box after a renowned sword master famous for the Tsubame-Gaesi technique, reflecting the weapon's connection to swordsmanship and its ability to wipe everything clean.
