[Western Crossover] My Days Running a Clinic in New York with Batman

A mysterious clinic appeared in New York one night, instantly becoming the city's number-one urban horror legend.

They say the clinic's attending physician is a two-meter-tall, terrifying bat monster; Dr. Strange, who handles the surgeries, is a rambling Parkinson's patient; and Misty

"The battle damage... The cost of damaged furniture has gone way over budget this month." Bruce sat bolt upright. "Misty, you can't keep these Hounds of Tindalos as pets."

Misty: "You should know I've never kept them as pets. That's why they eat the furniture."

"The living expenses are over budget, too... Misty, why is there an anglerfish on the grocery list? Is this what you meant by eating fish without thinking?"

Misty: "You can't blame me for that. Strange asked for the anglerfish."

A certain sorcerer and doctor: "I did ask for it."

The bat: "..."

"Misty played with the Flame of Y'golonac in the backyard, reducing the whole yard to scorched earth. Losses: ten square meters of lawn, two chairs, one table."

Misty: "That Stark guy who came in for treatment said we should play with it! He insisted!"

"In the end, the main reason our startup failed was that we kept an Outer God in the clinic," the long-faced sorcerer concluded.

Misty sighed. "If Bruce hadn't disbanded my followers, we should be living happily now, with no worries about food or drink."

To save face, Misty still decided to devote herself to promoting the clinic.

New York, midnight. A handwritten flyer lay quietly on the street:

Specializing in infertility, severed hands and feet, demonic possession, difficult-to-diagnose illnesses, air conditioner and TV repairs, drain unclogging (crossed out), and beating up aliens

The cold mist of night caresses the faces of those who come. In the shadows, something is licking at your heels.

The "Misty Clinic" sign flickers with an ominous gray-green light. Beyond the shattered glass door lies a darkness that devours all who enter...

A note by the entrance:

Please scream.

The second line of the note:

Reader's guide:

1. There aren't many things you need to know. This is a goofy story with Lovecraftian elements. The heroine is a non-human being, and the main cast may include some horror-movie elements in addition to the superheroes.

2. The pairing is Batman, but the story mainly focuses on construction and antics. The romance takes up practically no space.

3. Early on, the story takes place in the Iron Man and Spider-Man universe. The very righteous Justice League and Batfamily will also make frequent appearances later on.

Theme: Keep striving step by step through adversity, and you will eventually find the light.
