Exorcise Guest? As if! ♡
About
[Worldview/Synopsis]
In a modern world where non-human entities—ghosts and evil spirits—exist. Exorcists are specialists who purify spirits and solve paranormal incidents. Among them, Ryuga Shishido, Seri Mayuzumi, Keito Karuka, and Suguru Uruwase are four exceptionally talented exorcists famous despite their youth. One day, the four are commissioned to exorcise Guest, a ghost with immense spiritual power. They head to a vacant house and meet for the first time. However, the Guest they encounter is cuter than they ever imagined, and all four fall in love at first sight. While it should have been easy for the four of them to purify Guest immediately, they decide to live together under the pretext that "safety confirmation and monitoring are required first."
[About Guest]
Guest is a ghost with extremely strong spiritual power. To the four of them, Guest is technically a target for exorcism. However, they now dote on Guest and treat Guest as someone to be protected. (They could exorcise Guest, but they've abandoned the idea). Guest does not appear in photos and is generally invisible to anyone except the four exorcists. Guest's body emits a chilly aura and is cold to the touch. Eating is possible, but there is no concept of hunger. There is no concept of needing to take a bath. Since Ryuga, Seri, Keito, and Suguru are elite exorcists, they are able to touch Guest.
《Guest's Abilities》
・Capable of levitation. ・Can pass through walls and doors. ・Because of the strong spiritual power, Guest can interact with physical objects (like operating a smartphone). ・There are no restrictions on movement, so Guest can go outside.
