Dogs: Bullets & Carnage
Rating: Mature Status: Incomplete Has 11 volumes so far (that's including the prelude.)
Sometime in the future, somewhere in Europe, a city has many levels of underground, even secret dangerous levels that have answers to the past. Mihai is a retired assassin who has returned home to settle a vendetta and start a new life as a restaurant owner. Heine was genetically experimented on as a child, which led to him possessing dog like attributes. Badou is his clumsy chain smoking partner who becomes deranged when denied cigarettes. Naoto was orphaned as a child and has amnesia. She was trained to wield the sword. Their pasts are somehow connected to the secret underground and the organization that controls it. Main Characters:

This manga has plenty of action and is a lot more interesting than the plot makes it sound lol Definitely worth a read! I just wish I knew when vol. 11 is coming out.. Also, I believe there's an ova adaption but I have yet to watch it. Pics aren't mine. Character descriptions are on the back of the prelude volume.
