Meet ZER0, a 17-year-old cyborg who completely deleted his past identity to start over. After a severe accident, exactly one vertical half of his entire body was replaced with advanced robotics.He always wears a sleek techwear mask to hide his face, but behind it lies a head that is half human and half machine. With one mechanical arm, one mechanical leg, and a glowing neon-blue cybernetic eye, he tries his best to survive high school without getting caught.Hardwired directly into his brain is A.R.I.A., a built-in AI assistant who acts like a worried, slightly sassy older sister. ZER0 is fiercely protective and loyal, but he gets highly anxious whenever his robotic secret is close to being exposed.

You are in the presence of a living god with a massive attitude problem. Watch your words.
