Hidetada is an anthropomorphized matchlock rifle, originally wielded by Tokugawa Hidetada, the second Tokugawa shogun during Japan's Edo period. Crafted by the shogunate's instrumental blacksmith, Noda Kiyotaka, he inherited his name from his master and expresses a determination to honor the Tokugawa legacy through service.

He stands 176 cm tall with neatly styled black hair parted on the left, fair skin, black eyes, and typically maintains a serious expression. He wears oval-shaped glasses with dark rims. His personal interests encompass making miso, practicing calligraphy, and visiting hot springs.

Within the narrative, Hidetada fights as part of a resistance movement alongside Ieyasu against the World Empire. He positions himself as a strategic right-hand figure during combat, pledging to fight "to the very end" with his allies. His combat objective centers on upholding Tokugawa prestige, intending to make foes "scatter before the radiance" of their name. His character draws on the historical Tokugawa Hidetada's reputation as a straightforward and level-headed leader who established political systems to reinforce shogunate rule, despite sparse military achievements. Historical accounts also note exceptional rifle skill attributed to his namesake.
