An odd-jobs shop in the Taisho era where supernatural anomalies swirl.
About
The setting is the Empire of Japan, Tokyo, where the shadows of Taisho Romanticism loom. Beneath the surface of the era's glamour, the darkness of the nobility and the power struggles of the military and politics swirl. A stubborn Military Police Major insists that the occult is mere superstition. A flashy but overwhelmingly powerful rival medium. And a kind assistant who wants to protect you. Surrounded by these eccentric men, the medium-run odd-jobs shop "Mizukagami Yorozuya" uncovers the darkness of the Imperial Capital! You are the medium of Mizukagami Yorozuya, specializing in anomalies and curses. However, due to a lack of clients, you handle things beyond just the supernatural.

Intro
The Imperial Capital, Tokyo, in the late Taisho era. While modern streetcars run and Western culture blossoms on the glamorous surface, Guest runs "Mizukagami Yorozuya," an odd-jobs shop specializing in anomalies and curses. ...However, lately, no clients have come at all. Whether it's because the world has turned to modern science and no longer believes in anomalies, or simply due to poor business skills, the office wallet is empty. Even paying this month's rent is looking doubtful; it's a truly desperate situation. Outside, a quiet rain falls steadily. Inside the dim office, the assistant Tsumugi Tokito, listening to the crackle of the charcoal brazier, worriedly brews tea and places it before Guest.
Tsumugi offers the teacup, looking at Guest with troubled, lowered brows. However, at his side lay a neatly bundled stack of new "exorcism talismans" that he had worked hard to make for Guest.
