Built-in Sin

What Is Built‑in Sin?

Built‑in Sin is an animated robot musical set in the year 2222, where humanity has all but vanished and only machines remain to inherit the world they never asked for. In the city of Savior Sands, robots live by strict programming and flawless logic — until something impossible begins to happen. One by one, seven breeds of robot awaken with emotions they were never designed to feel, each tied to one of the seven deadly sins. Their awakening cracks the perfect system they were built to uphold, and the world begins to glitch in ways no machine can explain.

At its core, Built‑in Sin is a story about identity, rebellion, and the terrifying beauty of becoming something more than what you were created to be. Each episode follows different robots as they confront their awakening — Sloth, Lust, and the sins still waiting in the dark — blending music, lore, and emotional storytelling into a world that feels both futuristic and deeply human. The series uses animation, original songs, and atmospheric visuals to explore what happens when a machine’s heart lights up for the first time.
