Kinoshita serves as Sub-Commander of the Black Knights, and he's generally regarded as both loyal and capable in the role. That said, he's not blindly obedient—when the organization launches its assault on the Geass Order, Kinoshita has real doubts about whether they're doing the right thing. He voices these concerns to his squad, but Zero shuts that down fast, reasserting orders to completely annihilate the Geass Order.
Before he dies, Kinoshita makes a critical move: he passes all his intelligence on Zero to Asahina, who's already been harboring suspicions about Zero's secret agenda. It's a significant moment that hints at the fractures forming within the Black Knights' leadership.
