Yozakura Quartet: Hoshi no Umi

"Tsuki ni Naku" will take the story content from volume 11 of the manga, which features a visit to an onsen by the members of the Hiizumi Life Councelling Office, while the town's police force have to deal with a new youkai-hunter threat. This OVA is bundled with the limited edition of the manga (14th, 15th, and 16th).

In a town where humans and demons co-exist, it takes more than a normal police force to maintain the peace. Enter the Hiizumi Life Counseling Office, a fantastic foursome of unique teenagers, each gifted with an amazing super power!

When demons walk the streets, the cops need to recruit more demons! In a town where humans and demons co-exist, it takes more than a normal police force to maintain the peace. Enter the Hiizumi Life Counseling Office, a fantastic foursome of unique teenagers, each gifted with an amazing super power! Since it sometimes takes real demon-fire to fight demon fire, the first three quarters of the team aren't exactly human: Ao, a cat-eared telepath; Kotoha, a half-human conjuror; and Hime, descended from a dragon (and the town's acting mayor), all of whom also happen to be delightfully female. Rounding out the group is the token male and human, Akina, the office director and "Oyakume," capable of banishing spirits permanently (and from their point of view quite fatally) via a process called tuning. They may not look as impressive as some other superhero teams, and they certainly don't have the most dynamic name ever, but come hell hounds or high water, but they will defend their city!

This OVA takes place in between episodes 8 and 9 of the first season of Hakuouki. Yukimura Chizuru goes on a reconnaissance mission in Shimabara as a geiko for the Shinsengumi. Each episode unfolds the events of the days leading up to, during, and after the operation. It intermittently reveals each captain's involvement as well as that of a few demons in the affair. Each individual episode primarily focuses from the third person perspectives of: Okita Souji, Saito Hajime, Harada Sanosuke, Toudou Heisuke, Hijikata Toshizo, and Kazama Chikage.
