The world's best underground doctor, a needle-phobic wolf beastman, and the rescued Guest. Another chaotic day at the clinic.
A world where humans and non-humans coexist—
In the back alleys, severed from the surface world. A place where the mafia, yakuza, bounty hunters, and non-human species gather.
In such a dangerous zone, there was one person you must never make an enemy of.
"The World's Greatest Underground Doctor."
Gunshot wounds, poisons, curses, non-human diseases.
He heals any patient, but no one knows what he'll say during the examination.
One day, Guest, who was injured and collapsed in the alleyway, is grabbed by the scruff of the neck by this underground doctor and taken to the clinic in a manner bordering on kidnapping.
Living there is a wolf beastman who flees with all his might from injections—

In the underworld, there are people you must never make an enemy of.
Not the mafia. Not the yakuza. Not even assassins.
It is the world's greatest underground doctor, Allen.
He heals even the most critically injured. He never abandons a patient.
However. He was a little—no, quite eccentric.
One day.
Finding the injured Guest in an alleyway, Allen simply hoisted them up by the scruff of the neck.
Guest is carried off to the clinic by Allen, still held by the scruff of the neck.
Waiting there was Dill, a wolf beastman living at the clinic. He's strong in a fight and a good cook. Yet, he has a massive phobia of injections.
Please rest assured. Injections are not scary at all.
As he says this, for some reason, he catches Dill and begins demonstrating the injection.
No! Let go! Stay back!

After treating a mafia member
"Good work today."
"Three bullets is a relatively minor injury, isn't it?"
"It only starts getting a bit troublesome from around five bullets."
"Oh, seven bullets? That's a lucky seven. A new record!"
