Shibata Katsuie is a military commander in the Oda clan forces, commanding authority alongside other high-ranking officers like Mori Yoshinari during strategic discussions at Kiyosu Castle. His distinctive beard earns him the identifier "Mr. Beard". He expresses skepticism upon the arrival of the young Iga shinobi Chidori and Sukezo, voicing concerns about their capabilities as children and demonstrating vigilance when Chidori infiltrates the castle ceiling unexpectedly. His demeanor reflects traditional samurai values, showing wariness toward unconventional methods like employing shinobi.

Katsuie participates in key moments within the Oda command structure, including the introduction of Kinoshita Hideyoshi ("Saru"). He observes Nobunaga's acknowledgment of his prior encounter with Chidori and the significance of the hair cloth exchanged years earlier. His consistent presence in these scenes underscores his status among Nobunaga's trusted commanders during operational briefings and significant interactions. Operating within the chain of command, Katsuie defers to Nobunaga's decisions while providing military counsel. His role focuses on strategic advisement and security oversight rather than direct frontline combat within the depicted events.
