I must confess that I'm super confused by the multiple versions of these figures, but does your preordered Light come with the smirking head? If so, I'd like to take over your Giantoy preorder please! The only old listings I can find for Light say "One headsculpt" but the youtuber's review shows the smirking head in the box with regular Light.
There is basically three listings
Light (school outfit) - which includes both headsculpts
Light (black suit) - includes a body, black suit and some hands etc. this one has NO headsculpt
L - only one version, so includes everything
Then there is an UP version for each which has a silicone body instead of jointed
