Monster Killer

Monster Killer is an American comic book series published by DC Comics, though it doesn't take place in the same world as DC's other works. The series follows a ronin warrior whose entire goal in life is to hunt down and kill yokai, demons, and monsters in general.

Synopsis
Itsuo, a ronin warrior who watched his parents be murdered by yokai when he was young, has sworn to find all monsters and kill them all for what they did. He lives in a small fortress full of other ronin and ninjas who all have a similar goal to his own.

Main

 * Itsuo - the main protagonists of the series who despises monsters and, due to his anger, has a fear of magic, meaning he has to take on monsters with nothing but his sword alone.

Recurring

 * Jokichi - the head of the fortress who tries to remain positive even in the worst of situations. He was once a samurai but his master was sadly murdered.
 * Ichiko - a ninja who is very untrustworthy of people due to her past as an abused prostitute, though she later begins to warm up to people a bit more.

Antagonists

 * Nurarihyon - a yokai who is able to summon and control other yokai and demons, making him their pseudo-king.
 * Yamata no Orochi - an eight-headed and eight-tailed extremely large dragon.
 * Oni - one of the more common yokai who is a large demon that usually carries a kanabō.
 * Noppera-bo - a faceless spirit who enjoys pranks and is more of an annoyance than a real threat.
