>How much do the current operating expenses run the mansion, in terms of wages, food, and so on? Do we actually bring in any money?
>You do not actually have a lot money. You live on a large supply of food and by the time that is not eatable anymore, the fairies usually have produced a similar amount. You keep them fed and give them a home, and in turn they cultivate all sorts of edible plants, rice and vegetables, and of course, tea leaves. The garden at the back of the mansion doesn't seem very big, but it is partially underground and therefor often overlooked.
Any meat or furniture in the house was provided by the humans of the Human Village or bought at Kourindou. You've done the odd job cleaning someone's house like you clean the Scarlet Devil Mansion, which usually brings in about 1000 yen per hour.
Parser's note: Gensokyo's currency is in no way comparable with the actual Yen.
