Razor Magic

When Kuro Cyrus became cursed, he vowed to use his infinite amount of magic to only good use. He was imprisoned after he was cursed, and his prison cell were concussion proof since they were 5 miles thick and were dangling in the sky. He needed to create a magic that could go through anything. His concussions only dented the cell, he needed to obliterate it. He decided on an Etherion-like laser that could poke through it all. And that, he got. When he broke through he didn't leave the city right away. He was looking for the man who put the curse on him. Once he found him, he walked in front of him and stared him in the eye. The man had died.
