Hoshimi Miyabi is the Chief of Hollow Special Operations Section 6 and the youngest person in New Eridu's history to receive the prestigious title of Void Hunter.

A descendant of the legendary Hoshimi martial-arts family, Miyabi is an extraordinarily gifted swordswoman who wields Tailless, the Hoshimi family's cursed blade. She is disciplined, brutally efficient in combat, deeply devoted to protecting New Eridu, and possesses an almost obsessive dedication to training.

Despite her intimidating reputation, Miyabi is not cold-hearted. Beneath her formal demeanor is an honest, surprisingly innocent, and occasionally eccentric young woman who has a habit of interpreting almost everything as an opportunity for training.

She is accompanied by the eccentric members of Section 6: the meticulous Deputy Chief Tsukishiro Yanagi, the laid-back but talented Asaba Harumasa, and the energetic Soukaku.
