Devil May Cry
I've just noticed incredible similarities between this film and the PS2 game Devil May Cry. In fact, the two have so much in common that I have come to the conclusion that Capcom originally wanted to make an Urotsukidoji game.
Heroes- Amano Jyaku. A half man half beast warrior who fights demons. Dante, a half demon mercenary who fights demons. Both have an attitude and transform into super creatures when sufficiently angered.
Main villains- Nagumo and Mundus are both huge winged demons with a third eye that shoots red beams AND both of them end up having the hero fly at them and rip into their heads.
Side characters- Megumi and Trish are both tough yet vuluptuos women with a lot of cleavage with some blood relation to the main hero.
Suikakuju and Angelo are both horned yet elegant warrior demons serving as recurring obstacles for the hero.
Captain, although your abilities intrigue me, you are quite honestly inferior- Khan Singh
