A clan devoted to protecting the Reincarnation Sphere. When Kagura's reincarnation draws near, they appoint a priestess to watch over her.
Year of Goshin
When a child from the Goshin Clan is born in this year, that child becomes a priestess, chosen to protect Kagura. The timing is such that Kagura reincarnates shortly after the priestess comes of age.
Naraku is not a name, but the title of the person appointed to watching over Kagura and the Reincarnation Sphere.
From a young age they will spend all of their time except meal times sitting and watching over the sphere until Kagura is born.
Afterwards, they will accompany Kagura and ensure she is able to obtain Red Orbs so that she can mature into her true form and exterminate the Yōma.
- According to Senran Kagura: Estival Versus, Naraku is from the same village as the Mikagura Sisters, Renka, Hanabi, and Kafuru. Though they likely wouldn't have encountered Naraku due to her duty of sitting and watching over the sphere full time (alternate timelines not withstanding).
