Sasuke, a clockwork ninja forged by the Wise Old Man of Iga, functions as both guardian and tactical commander of mechanized ninja legions. Initially encountered as a castle sentinel opposing protagonists Goemon and Ebisumaru, he engages them in aerial combat atop a massive kite, leveraging acrobatic precision and razor-edged kunai before his defeat. Post-conflict reconciliation reveals a misunderstanding, prompting his transition into a loyal comrade aiding the group’s quests to stabilize peace.

His core programming merges unyielding loyalty with guileless trust, frequently misinterpreting irony or subterfuge. A concealed toggle in his design can override his benevolent protocols, activating a ruthless, destructive alter ego—an unexplained safeguard embedded by his creator. Despite this latent volatility, he displays unexpected affection for simple pleasures: steamy herbal baths, bitter matcha tea, and idle relaxation, humanizing his metallic composition.

In combat, he specializes in kunai barrages and parabolic explosive projectiles, tactics diverging from his allies’ approaches. Though his concept nods to Sarutobi Sasuke—the folklore shinobi famed for simian dexterity—his capabilities derive solely from gears and pistons rather than myth. Missions highlight his strategic flexibility, frequently coordinating with Goemon, Ebisumaru, and Yae to dismantle adversaries through synchronized assaults.

Formerly the Wise Old Man’s jounin overseeing automaton soldiers, his journey shifts from dutiful enforcer to steadfast companion. Subsequent endeavors involve repelling imperialist forces like the Peach Mountain Shoguns, who threaten Japan’s cultural identity with Westernizing agendas. While anchored in solemn duty, his interactions intermittently veer into humor, particularly when parsing figurative language or prioritizing leisure rituals amid chaos.
