Light (aka, for some reason, 'Sharp') is Dr. Cinnamon's Grandson, pilots Twinbee and the main protagonist in TwinBee Series. So as to ensure that this fact is never ignored, he wears a blue jumpsuit embossed with the letter 'T' and has never been known to choose any other outfit. Whether he's an orphan and, indeed, why he lives with Cinnamon is unclear. Light spends most his time behind the scenes, as it were, generally appearing in the cut-scenes that appear between game levels. He also goes missing in TwinBee RPG.
