only 2 episodes out atm.
Basically ... Oni vs some other group... Humans killing Oni and Vice versa. Basically two factions going head to head with each other. Oni baby gets saved from a member of the opposition etc... thus story begins.
Some action, blood (understatement), some rivalry and other antics from similar anime, you will get to know what I mean when you watch the second episode... not really my cup of tea, but I will carry on watching it.
