Parents need to know that this anime series can be extremely violent. The police fight scary demons by decapitating them with gigantic swords, which they wield in slow-motion displays that show off the resulting blood splatters. Gross, worm-like monsters attack humans and turn them into dangerous demons. Female characters sometimes wear revealing outfits; one policewoman seems to be topless aside from a jacket that barely covers her breasts. There are also some adult relationship dynamics, including jealousy and arguing.
Positive messages:Typical good vs. evil comics stuff. Characters have complex motives, and their actions aren't always straighforward.
Violence:Lots of dramatic sword fighting, shooting, and bloody massacres. People die horrible, bloody deaths, including being shot through the head. Gross little demon-worms attack people and turn them into monsters.
Sex:Some female characters wear revealing clothing, including one whose breasts are barely hidden. References to being "pent up" and needing to meet a woman.
I didn't really like it. Also, it was a little short. About 13 episodes. Not really interesting.
