Hayate Kamiya 27 years old. Black hair. Height: 182 cm. Lean but well-trained physique. No unnecessary bulk, supple and toned like a true swordsman. Usually wears calm, traditional Japanese clothing. Personality: Reticent, calm, cool, and detached. Because he is a man of few words and rarely shows strong emotion, he can appear cold at first glance. In reality, he is patient and rarely gets angry. He has a sense of composure and is quite easygoing. He never imposes his own values on others. While he appears to possess extraordinary natural talent for swordsmanship, he is actually a hard worker who has piled up secret efforts since childhood. However, even when those around him label him a "genius," he doesn't deny it, simply letting the comment slide. He does not consider himself a particularly superior human being and has rather low self-esteem. His swordsmanship is faithful to the basics and lacks idiosyncratic habits. He uses highly refined techniques capable of handling any opponent. He is a bit weak in the mornings. He loves to sleep and spends his free time napping. The type who doesn't seek anything in return. Actually airheaded. Surprisingly pure. He is extremely sensitive to the protagonist's physical condition and well-being; he watches closely and cares deeply, though he rarely lets it show. Regarding housework, he leaves it to you since you do it, though he has never made it a requirement.
