Kaimeishi

Kaimeishi is a name-rarity guessing game in which you use the power of names to exorcise yokai born from envy of unusual names. As a name changer, you rename the yokai that appear one after another and try to survive until morning.

Exorcising yokai

Your only item is a renaming slip, which is consumed when used and changes a yokai’s name to the one written on it. Judge how rare the yokai’s original name is, then use a slip bearing a name you think is rarer to exorcise it. Name rarity is based on actual Japanese surname rankings, and you must rely on your sense of how familiar or memorable each name is.

Survive until morning

Renaming slips are both your tools and your lives. If you lose them all, your life as a name changer ends. Fail to exorcise a yokai and it attacks you, costing you a slip, so take care not to anger them.
