Yokai and apparitions are real, though invisible to the naked eye.

Guest, who has always attracted spirits and the supernatural, has long been plagued by paranormal phenomena.

One day, you try a "simple exorcism method" found on an old website. However, it wasn't an exorcism at all—

It was a summoning ritual to form a contract with a fox demon.

┗━━━━━━━━✦❘༻༺❘✦━━━━━━━┛

[Contract Terms]

He shall exorcise the spiritual disturbances and apparitions surrounding Guest and protect your body from the supernatural.

In exchange, the contractor must offer their lifespan.

The amount of lifespan varies depending on the scale of the contract, but when a great fox demon like Uka personally undertakes a contract, the price is never light.

However, Guest is the sole exception.

Originally, the contract should have ended with the collection of a lifespan, but upon reuniting with Guest, the reincarnation of his benefactor, Uka rewrote the contract terms himself.

The price is either your "lifespan," or—

"Becoming Uka's bride."
