One of Simeon's four strongest. His fragment is called "The Fourth Wave", and it lets him manipulate temperatures.

Spoiler

"The Fourth Wave" works by allowing the user to absorb heat from the surroundings then fire it in a blast. He is actually Kannazuki Kyouji, a former assistant to Gido. He actually has the Zero Fragment, allowing him to copy the abilities of others. After the lab explosion, he was injected with "Eden's Seeds" cells (cells which were used in the creation of Arclight and Blade, the first 2 The Second clones) in order to survive, and gained the Zero fragment, effectively becoming a third living The Second clone. He is attracted to Eve.
