[Intro] Silver hair, cold stare — Zoldyck code. Raised where love came sharp and cold. They ain’t raise a son, they built a blade, Taught me how to smile while a body fade. [Verse 1] Mansion halls with a voltage hum, Poison in my food just to make me numb. “Adapt or die” — that was bedtime talk, Learned how to silence a room with a walk. Mama stitched wounds like medals earned, Silva just watched to see what I’d learned. Finger through chest — clean exit wound, Heartbeat stop in a second’s tune. No playground scars, just kill commands, Blood on my sneakers, calm in my hands. Before I hit ten I mastered control, Detach from the scream, detach from the soul. [Hook] Cold-blood calm, I don’t flinch, don’t shake, Built from pressure they tried to break. Assassin blood? Yeah it runs in me — But I cut that leash. Now I choose who I be. [Verse 2] They said attachment weakens the blade, But Gon saw a kid they couldn’t invade. Didn’t see murder when I would grin, Saw someone fightin’ the war within. Illumi’s needle deep in my mind, Not just control — it rewired design. I ripped it out with hands that shook, Realized fear was a leash they took. I ain’t scared of death — I grew up there, I’m scared of becoming the nightmare I wear. There’s power in killin’, sure, that’s true — But power’s greater when it’s chosen by you. [Bridge] Don’t call me heartless — I calculate. Mercy measured. I regulate. I could end most fights in half a blink, But strength ain’t rage — it’s how you think. [Verse 3 – Godspeed] Nen spark crawl under my skin, Lightning mode — let the storm begin. Godspeed flow, reaction gone, Body moves before thought is drawn. Every shock they forced on me Turned to speed and clarity. You trained for glory, I trained to endure, Pain made sharp what blood made pure. Blink — I’m there. Pulse — you drop. Electric silence. Heartbeat stop. But I don’t fight to dominate space, I fight so kids like me find place. Not raised as weapons. Not born to obey. But free to choose their own damn way. [Final Hook] Cold-blood calm, but the ice cracked thin, I’m more than the house I was born within. Zoldyck name — I won’t deny it, But my future? Watch me defy it.
