Wakeari Bukken Ni Wakeari

Harumi-chan, a young office worker who always yearned to live alone, begins to do so in a supposedly haunted apartment. Even when her items began to move on their own, or when unusual phenomena occurred not a single thing phased her.
However... a weird guy with fox ears suddenly appeared right before her!?
...or to be more precise, Kurogane, the Yokai who lives in her "haunted" apartment appeared!
"Even if he’s a Yokai, there's no way I'm letting him stay rent-free!"
Taking turns with the cleaning, laundry, and even the meals -- the two of them, having signed a roommate contract, begin their bizarre, exciting, and fluffy life together!
