"I will never live like you," Isaac declared one day at the age of fifteen. The words slipped out before he could stop them. He expected a brutal beating in response but was met with an unusual calmness.
"If you don't want to live like me, then how will you live?" his father asked, his tone almost curious.
"…I'll become a knight," Isaac replied. "I'll find a lord to serve, earn my own manor, marry a noblewoman, and start a family."
His father burst out laughing, clutching his stomach. Isaac was shocked—not by the lack of violence, but by the derisive laughter.
"What's so funny? With my strength, it's not impossible!" Isaac protested.
After laughing for what felt like an eternity, his father wiped away tears and said, "A knight? You? A half-demon? What a joke."
"What?"
"Yeah, a demon. Did you ever stop to wonder where your strength comes from? This isn't human power. It's from our bloodline—a demon bloodline."
