The story is set in Belmonte Calabro in Italy. Belmonte is the city of filled with Automatas and boasts the biggest number of Automatas produced a year.
Automatas are androids. Mechanical beings created from nothing. Most Automatas can be easily distinguished from humans due to their robotic faces but there are the Antique Dolls, which looks exactly the same as humans with only their eyes giving away who they really are.

You start off as Romeo, a slack taxi driver who absolutely stinks at going around the city with his taxi. Or that’s what he looks like from the outside.
But the truth is, he’s a runaway werewolf from the Orma Rossa, the only remaining werewolf clan.
He lives together with Anna, an Antique doll he picked up from the dump after he left the Orma Rossa. She doesn’t have any memory of the past. So she’s living happily with Romeo.

But pleasant times never continue for long. Orma Rossa do not feel like ignoring Romeo any longer and the group called Luparia (the archnemesis of the werewolves), is moving behind in the shadows. Romeo will find himself surrounded by both new and old foes. This time, their target may not only be him… ...

Yuzuki came to the town of Yuunagi as the leaves were starting to change colour. The first person he met was a cute cat-eared waitress, who was handing out pamphlets on the street.

“T-This is Cafe Setaria. Please come in!”

When he was led into the cafe by the waitress Chieri, the other girls there also had animal ears. Seeing his wondering look, they worriedly asked him:

“Could it be… that you could see these ears?”

They explained that they were actually hybrid beasts whose ears and tails cannot be seen by normal humans. After learning about their secret, he started working at the cafe with them, while being both shocked and impressed at the differences between them and humans. ...

After bumping into a literal angel on the street, she proceeds to lecture Takeshi for carrying around "foul" and "inappropriate" material. Her holier than thou attitude is easily explained as she is fresh out of the golden gates. Her demeanor quickly changes as she collapses having expended too much energy from being on Earth. Being a good Samaritan and all, Takeshi brings the angel back to his apartment so nothing naughty happens to her if she is left alone outside.

Charlotte wakes up after you bring her home because your immense lust rouses her. She explains the way she can get enough energy to make the trip back to heaven is through the "love" of humans to recharge. Being a pent-up single guy living on his own, Takeshi has A LOT of love he can pump her full of! ...

20XX A.D. Japan is plagued by evil spirits that dwell in the shadows.

The only thing preventing chaos between spirits and humans
is an implicit agreement to "live and let live", but corrupt organisations
make deals with the demons. Crime syndicates go supernatural.

The nation is in decline, and those who walk the path of goodness
don't last long in a society of rampant heresy and sin.

Thus, the government empowers certain individuals to fight fire with fire.
Agents may do evil... against evil... in the name of good. Exorcists with a license to kill.
They are called the Taimanin. ...
