"Impossible!" Sebastian said out loud.
Levi's skin tore, melting and dropping on Abby's body as his transfigured skin was undergoing a certain change. He cried out loudly every time it hurt wildly, but didn't fail to keep straining himself. That sound, similar to a hiss of a train, was produced by his body and intensified with every peeling layer. It felt as if his energy was melting, the skin dissolving into liquid and seeming to evapourate into the air.
But none of that was really true. Instead, Levi's whole configuration could be said to have been in the process of rewriting, everything taking a new form as his body convulsed with tensing and retracting muscles.
As the process continued, Levi could hear Lexi's voice, his glow bright like a dome on the horizon.
[Impossible, Levi]
[You will kill yourself]
