<p>1. IMHO this is probably a case of "wholesome crossdresser" or trap... the disguise is symbolic of his desire for anonymity, not a gender identity. Take that and the sorta-stereotypical flamboyant OD, and it becomes pretty clear that while Crowds wanted to be "edgy" displaying a spectrum of sexualities, they didn't go very far... at all <sup>[see: the fanservicey pseudo rape scene Rui received]</sup>.

Their feminine outfits appear to be reserved mostly for leaving the house as LOAD GALAX."</blockquote>
