Kiho Shimada is an archaeologist at a prestigious university, part of a research project for ancient texts. Upon deciphering a series of texts written in several forgotten languages with the assistance of an automated system, she comes under scrutiny for potentially defiling them. With her career on the precipice of disaster, she meets Genta, who can seemingly write in one of the forgotten tongues. He promises to show her the truth of the legends she has uncovered, but in order to do so she must meet his family - a family of gods.
