Yôjo densetsu Seirên X: Mashô no yûwaku

True I've only seen three (there are eight and this is number six) but this one wins because of Yuma Asami. As others have said, she is gorgeous and I think these kinds of films depend a lot on the leading lady. Also the cinematography is better compared to the other two I watched... that isn't saying much since it still isn't that great but hey this is grading on a curve. Yeah nobody cares about the cinematography... how hot is Yuma Asami? Very hot and the story moves at a decent pace. Can't believe I'm talking about the story in something like this but there is more of a story than say Red Account: My Bloody Angel (1988). True still not much of one and like another reviewer pointed out, they could've done a lot more with the supernatural aspect but still I prefer this over New Siren (aka Siren 5 aka the one from 2004) or Siren XXX: Magic Pleasure (aka Siren 8... the final one).
