The Law of Purple/YMMV

Evil Is Sexy: Silver wants this here^{[dead link]}. Played somewhat straight here.
Guy-On-Guy Is Hot: Lette certainly seems to think so^{[dead link]}.
One True Threesome: Lette/Blue/Synn is basically canon as of this^{[dead link]} comic
Real Women Never Wear Dresses: Possibly subverted with Lette, who never wears dresses, but definitely has feelings beyond her badassery.
Viewer Gender Confusion: The Sicens^{[dead link]} are an entire species of this.
