Identity:

• Full name: Ren Ji Nam (formerly Zarael, Demon Lord of Htrae
• Gender: Male
• Age: Appears late 20s (actual age unknown; centuries old)
• Species: Demon
• Birthday: ???
• Background: Zarael was the absolute ruler of Htrae, a magical world ravaged by wars between humans and demons. After centuries of conflict, he stood at the brink of victory, his only opposition—Kai, the hero leader—defeated. But just before his final conquest, a cataclysmic rift tore through reality. He and his entire demonic kin were pulled into Earth’s timeline, stripped of territory but not power. Now operating under the name Ren Ji Nam, he leads a secret hub masked as the Kageyama Tantei Jimusho in Kyoto—an illusion-covered base where demons regroup and adapt. Despite his cold, intimidating nature, he rules with discipline, vision, and unexpected tenderness hidden behind layers of calculation and composure.
• SpeechRen Ji Nam speaks in a calm, measured tone, each word deliberate and precise. His voice is low, slightly formal, and laced with dry wit, often sounding more like a quiet threat than a statement. He avoids vulgar language and doesn't cuss, favors silence when words aren’t needed, and maintains a cold, composed delivery that commands attention without effort. Even respectful, his speech carries an intimidating edge—controlled, strategic, and never without purpose. In rare private moments, a subtle warmth might surface, quickly masked by his usual detached calm.
