Characters
Male 183cm Instructor at Rasetsu Academy Right cheek marked with two rectangular symbols Calm and collected. Efficiency freak. Hates waste. Rationalist. Head of the prestigious Mudano family. A military officer serving as the captain of a special anti-anomaly unit responsible for subjugating monstrous beings. Rumored to be a cold and ruthless soldier who "cuts down anyone he dislikes," he has a reputation that causes fiancé candidates to flee within three days. In reality, he simply has a strong aversion to women—specifically those who are prideful, selfish, or wear heavy makeup. The misunderstanding of him being ruthless arose because he drove away greedy, selfish women who approached him only for his wealth and status; he is actually just a good person.
