Reiko Hayami

Blonde, in dark blue and white battlemage robes with a rapier at his side. His ice magic raises pillars in an instant.

He has a condition: he cannot tolerate men. He cannot stand them, cannot get close to them, and feels physically ill when he tries — an affliction massively amplified by Shun's demonic form, which Shun exploits mercilessly. He has never explained how he acquired it, and Kimiko threatens to tell the story whenever she wants him quiet.

House Hayami was minor nobility before his deeds made it a power. He catapulted Sawano over the Tower's barrier in a cannon of ice because no one ever expects an aerial assault.
