Originally named Hikari, so you will see this name in some of his trivia. Luka is one of the three protagonists of "Search for the Sky".

Not much is known about his family. He currently lives with Kirsty, the woman who took him in. He is one of the Gifted, but even he doesn't seem to realize what he is or what that means. Luka is bumbling, awkward and generally laid-back to the point where he could even be considered a bit of an air-head. But there are times when he becomes uncharacteristically fearful and aggressive.

Relationships with other OCs:
Joel - The two frequently butt heads, but Luka generally tries to get along with him.
Michi - Very attached. Luka dotes on her.
