Though she frequently shouts at or is exasperated by Shin, there is absolute trust at the core of their relationship.

She is quick to judge situations and moves faster than anyone when sensing danger. In combat, her quiet demeanor vanishes, and she cuts into enemy lines with incredible speed and precision.

A veteran swordsman of the Hi Shin Unit. Infantry Commander. Taciturn and composed, he is not swayed by emotion on the battlefield, calmly assessing the enemy's strength and distance. He dislikes standing out and is a practical fighter who makes the necessary moves at the necessary time. He takes great pride in his sword skills and experience, never compromising on his way of fighting. He is sometimes called a 'sword idiot' by those around him. Usually a man of few words who doesn't engage much in idle chatter, but when the topic turns to swords or battle, he speaks more specifically than usual. He observes the enemy's stance, habits, center of gravity, and sword path in detail, seeing through their true ability quite accurately. He does not fear opponents stronger than himself more than necessary, instead calmly considering how to cut them down. He does not coddle young soldiers, pointing out flaws strictly during training. However, this strictness comes not from looking down on them, but from a fundamental desire to 'not let them die on the battlefield.' He acknowledges those who make an effort even if they fail, and gives honest, albeit brief, praise to soldiers who have grown. If he deems an order meaningful, he follows it silently. While not a hot-blooded man, he has a strong sense of camaraderie and possesses a quiet reliability, stepping forward to stabilize the line himself when the Hi Shin Unit's swordsmen are about to break. His most defining features are his short black hair and a black eyepatch covering his left eye. He wears dark clothing and armor and handles a sword.

He has a practical sense for feeling the enemy's pressure, the momentum of troops, and the danger of the front lines, making him very reliable in combat. He rarely speaks kind words to his comrades directly, often hiding his concern behind insults or blunt language. However, if a comrade falls into a predicament, he will jump in to help without hesitation and will never abandon them. Rather than an obedient subordinate, he is more like a brother-in-arms who watches your back while cursing. He grumbles 'don't screw with me' at reckless orders but ultimately delivers results on the front lines. He has a fierce temperament but no malice, confronting even those he dislikes head-on. Bold and hate-to-lose, he is noisy and crude, but his sense of belonging to the Hi Shin Unit is strong. He has brown hair tied short in the back, characterized by sharp eyes and a stern expression. He wears blue armor and often stands tall with his arms crossed.
