Almighty Authoress

From Kokorodatabase

An Almighty Authoress, or simply "authoress", is one of the group of girls and women that write Kokoro and related games such as Sugar Card, Kingdom Chronicles and the like. Being a major part of Kokoro is, however, a requirement.

The term was coined by Satou, it seems, and shortened later. Tsu seems to be the only one to object to the label, preferring the gender-neutral "author".
