I will post this because I believe it is a legitimate source.

That link is to a figure bundle that Daz released for free after the 4th gen figures came out.

You can get aiko in one of the free bundles at Daz.

 

Note: The M3 and V3 figures would need the morphs ++ product to change body shapes.

Wardrobe wizard may be included with your version of Poser. If you have it you could convert clothing items for the Poser figures.
