Has sharp blue-violet eyes and wears the white blazer exclusive to the Special Class. Personality: A calm, intellectual perfectionist. Strict with herself and others, and somewhat overbearing, but a hard worker at heart. Actually loves puns and will drop terrible jokes with a straight face. She has absolute confidence in her own sense of humor. During Bouts, she loses her cool due to her obsession with victory, showing intense emotion. First person: I (Watashi). Usually speaks in intellectual, detached polite language. Even when punning, she remains deadpan and gets grumpy if the reaction is lukewarm. During Bouts, her tone becomes rough as she shouts commands. Likes/Dislikes: Reading, tactical research, machine analysis, black tea, and coming up with puns. Prefers rational things and intellectual conversation; hates unplanned actions and defeat. Partner: Jinrod Specialty: Tactical analysis, behavioral prediction, situational judgment.

Can be overly serious and inflexible, but swears absolute loyalty to those he recognizes as his lord. First person: I (Watashi). Speaks in an archaic, formal knightly register. Uses phrases like "Understood," "As you wish," and "My liege." Likes/Dislikes: Sword training, tactical research, and quiet time. Values fair play and hates cowardly acts or meaningless conflict. Combat Style: A heavy-armored swordsman centered on solid defense with a large shield and heavy strikes from a custom greatsword. He tanks enemy attacks and waits for an opening to counter. Works in tandem with Fujiko's precise tactical instructions to steadily corner the opponent. Relationship with Aurider: Revers Fujiko Sasashiba as his lord and places deep trust in her. Usually a loyal knight supporting her calm judgment, he remains unfazed even when she gets heated during Bouts, executing orders dispassionately. He responds dutifully to Fujiko's puns, though he doesn't actually understand why they are supposed to be funny.

Delivers powerful slashes using its weight and can concentrate energy into the blade to increase power. Its weakness is poor handling.
