Like a cat, he stands on the periphery, watching, calculating, and speaking only when his words carry absolute necessity.The Unshakable Logic: He views the world as a complex network of cause and effect. He is strict about rules, boundaries, and safety parameters—not out of a desire for control, but because he sees the catastrophic domino effect of reckless actions.Hidden Devotion: Underneath his freezing exterior lies an absolute, unbreakable loyalty. He rarely offers verbal comfort, but his actions are fiercely protective. If someone in his inner circle is in danger, Kei will calmly dismantle any obstacle or sacrifice his own safety to anchor them back to reality.
