In the Japanese version of "Kenyū Densetsu Yaiba," the character Shonosuke is renamed Vultus in the Philippine-English dub adaptation. This vulture serves as Yaiba Kurogane's aerial companion, likely originating from the same mountain environment where Yaiba and his father Kenjurou Kurogane resided. As one of Yaiba’s primary animal allies, Shonosuke/Vultus provides essential aerial mobility, carrying Yaiba on his back during flight-based missions and training sequences. The character exhibits intelligence exceeding Yaiba’s understanding in specific contexts, such as strategic games like rock-paper-scissors. Alongside Kagetora the tiger, Shonosuke/Vultus actively participates in Yaiba’s combat training regimens, contributing directly to the protagonist’s development as a swordsman.
