[Completed]
Keluosha is a witch who dwells between life and death. She runs her own agency, helping the dead fulfill the wishes they left unfinished in life and preventing them from becoming vengeful spirits that might threaten the world.
Until one day, a soul claiming to be from 21st-century Earth knocked on her agency's door.
"Please, Miss Witch, delete every last file on my computer's hard drive!"
"Of course. But first, you have to tell me what a computer is... and how you got here."
From that day on, Miss Keluosha noticed that the scope of her agency's business was getting stranger and stranger.
"This is the Austuya Agency. For exorcisms, press 1. To clear a relative's debts, press 2. To erase your embarrassing past, press 3. To transmigrate into a beautiful girl everyone loves, press 4..."
"What? You want to come back to life and stab that bitch who cheated on you?"
"Of course! But it'll cost you dearly... and there will be an additional fee."
When the other party agreed without hesitation, Keluosha smiled knowingly.
