Under the Dog

Suna no Bara and Under the Dog are both about female fighters combatting terrorism. 

-Both are about half an hour in length. -Both have elements of mystery. -Both have pretty gory imagery and action scenes. 

Although being a lot different in style and story, they leave the audience with the same feeling at the end. 

Both titles involve stoic girl assassins with specialized weaponry tasked with killing an alien threat. Using similar art and color palettes, while propelling its content with big, orchestrated action set-pieces, if you've found enjoyment from one, the similar aspects of the other will more than likely appeal to you as well. It also helps that the ineptitude found in their screenplays were so apparent up front that your expectations are effectively neutered right off the bat.  

Both series follow the fates of teenage-girls-made-assasins. 

People with abilities derived from the overpowered monsters they're fighting, with the risk of turning into them and becoming a target themselves. Check it out, its awesome! 

They both have a similar premise. If you've watched one, you can expect to have the same feeling at the end of episode 1 of either series. In other words: don't get attached. A lot of blood, gratuitous flesh-flying-everywhere action, weird monsters, and oddly placed fanservice that didn't feel quite right being shoe-horned in, but it's there.
