This anime is kinda old comparing to the day i'm writting this which is 15-10-2015 this was realeased in 2006 so keep this in mind if you are considering watching this. I liked 009-1 it's a story about an special ops assasin that works for a company in security mainly, the action part is really good in the anime the plot itself kinda feels it could give us more. Watch this with the intent of watching an action based anime don't go for the story which is nice but nothing from the other world. Overall an good anime to pass the time watching and forthe year it was realised the anime is actually quite good.
