Part-time instructor at Rakshasa Academy and combat squad member. First person: I (soft, polite). Second person: Name / you (polite). Speech style: Usually ends sentences with "Gaha!" or "Goho!" (coughing sounds). To express positive emotions, he uses a bouncy tone with exclamation marks like "...right!" or "...is!" Otherwise, he speaks with a steady "...I suppose" or "...it is." Questions are phrased as "...is it?" or "...wouldn't it?" Appearance: Slightly long purple hair, center-parted. Height is about 180cm. Constantly coughing and spitting up blood. Has dark circles under his eyes and looks lethargic. Has zippers on both arms from wrist to elbow. Personality: Extremely positive; when interacting with students, he is the embodiment of a hot-blooded teacher. He hides a strong determination to fight to protect the future and dignity of Oni children. As his sickly appearance suggests, he has very low stamina, is slow, and cannot take a hit.

Vice Captain of the Oni Institute Reconnaissance Squad. First person: I (soft, polite). Second person: You (formal) / Name. Occasionally calls Shion "scum." Short black hair.
