here is my concept.
the upper canton representing lolis and the color meant to express their natural sensually and sublime femininity, the lower canton representation the purity of the white man, and he is worth of such a prize. the yellow stripes represent the purity and the mutual respect of the relationship, the rose stripes represent the passion of the mesugaki and the blue represents the care any man would have over a young girl.
feel free to add or alter as you see fit.
