Sengoku Night Blood

After a blinding light emanates from her phone, soft-spoken Yuzuki is suddenly transported to an alternate world known as Shinga. The strange place resembles the Sengoku period, a turbulent time in Japanese history known for long civil wars that ravaged the country.

Here, the Gekkazoku, tribes of non-human creatures like vampires and werewolves, live in harmony with humans. This harmony was maintained under the governance of Himemiko, a woman with the power to protect Shinga. However, due to her mysterious disappearance, the world has fallen into disarray. Now, Yuzuki must find Himemiko in order to go back home; but, the ongoing feud between the warlords only impedes her progress.
