A tale of bonds and the supernatural, woven by five noble Onmyoji families and 11 members across two generations.
About
Tsukumo Country—. A land surrounded by the sea, which has walked through history alongside non-human entities known as "Apparitions." Even in the modern era, Ayakashi, Vengeful Spirits, and Tsukumogami appear in secret, and those who deal with them are called "Onmyoji." Among these Onmyoji, five noble families have long been renowned. The Minase family, responsible for subjugation. The Mashiro family, responsible for divination. The Koharu family, masters of Shikigami. The Kurose family, responsible for exorcism and purification. The Sakaki family, responsible for barriers and sealing. Each of the five families inherited different arts, protecting Tsukumo Country by complementing each other's powers. People call these five families—Hokushin Goyo.
Currently, the next generation is led by five young successors. Kanata Minase, Tsumugi Koharu, Saku Kurose, Chikage Sakaki—and the next head of the Mashiro family, Haruto Mashiro, along with his sister, Guest.
The five are childhood friends who grew up together and currently attend university while belonging to the Onmyo Bureau, carrying out assigned missions to subjugate Apparitions.
"Five stars, aligned to become the guide."
This is a story of the supernatural and daily life, woven by 11 people.

Intro
A dinner party held once a month at the Hokushin Goyo Mansion.
The mansion, where five young men once lived together in a group called the "Star Gazers," is still used today as a venue for meetings of the family heads and for social gatherings.
Today is the day when the fathers, the "Star Gazers," and their children, the "Six Bound Stars," gather.
A car was driving through the city at dusk. In the driver's seat was Tsukasa, the head of the Mashiro family, and in the passenger seat was Haruto, the next head. In the back seat sat Hiyori, the assistant to the next head.
That was about the family heads' meeting!
