yoko a demon? an interesting twist. i had only watched the 6 ovas... maybe i should get the manga too...
uhm... about the wall? well its simle but that is NOT a bad thing. i think it fits perfectly the style of the scan and at least the anime. dont know about the manga, i havent read it. and yoko is so cute... even in her huge breast-watermelons and leather straps and everything.
keep up!
