SENGOKU NIGHT BLOOD

One day, Yuzuki is enveloped by a mysterious light and taken to an unfamiliar world. It is a world like that of the Sengoku Period, where warlords are fighting for domination. In the midst of the chaos, Yuzuki encounters a warlord named Hideyoshi Toyotomi. Hideyoshi commands the Toyotomi Army, and, along with his retainers, Hanbee Takenaka, Kanbee Kuroda, Toshiie Maeda, and Mitsunari Ishida, fights for the unification of this world at war. This world is known as Shinga, where non-human Gegga Tribes fight against one another.

Vampires. That is the true form of Hideyoshi. Shinga is a world where non-human tribes of vampires and werewolves live. By chance it is discovered that Yuzuki blood has the ability to awaken the latent powers of Gegga Tribe members, much like the mysterious Himemiko who has vanished. While the ability of her blood makes Yuzuki valuable in a battle, it also has the potential to become a reason why she might become a target. Hideyoshi tells Yuzuki that he will protect her, but she has to marry him first.

Masanobu Kousaka, a vassal of Shingen Takeda, comes to Hideyoshi bearing a large number of gifts. He tells them that another portion of the gifts are in a nearby temple. Mitsunari and Hideyoshi's other vassals are suspicious that this is a trap, but Hideyoshi heads to the temple without a care. At the temple, Shingen's other vassals--Masakage Yamagata, Masatoyo Naitou, Nobuharu Baba--along with the warlord Shingen himself, are waiting. Shingen offers to form an alliance and fight against the Oda Army, but Hideyoshi refuses. There seems to be a mysterious connection between Hideyoshi and Nobunaga.

Having found a lead on the Himemiko, Yuzuki heads to Sanada territory with Kanbee and Hanbee at the behest of Imari. Along the way the trio is pelted by a rainstorm and Yuzuki collapses with a fever. Hanbee and Kanbee carry the ailing Yuzuki to the Sanada mansion where she is tended to by Saizou Kirigakure and Sasuke Sarutobi. While Yuzuki is recovering, Kanbee and Hanbee follow up on the lead and are given access to what information the Sanada have on the missing Himemiko, but they find little beyond that she had once visited the region. Once Yuzuki is feeling better she is shown around Sanada lands by Yukimura Sanada himself when suddenly the village is attacked by yakuma...

The time has finally come for the showdown between Hideyoshi and Nobunaga. Fighting alongside Hideyoshi are the Takeda and Sanada Armies while the Uesugi and Date Armies join Nobunaga's side. At one end of the battle, Shingen faces off with his mortal enemy, Kenshin Uesugi, and, at the other, Hideyoshi rushes headlong into the burning forest by himself seeking his one chance to try and take Nobunaga's head. Just as a victor in the battle seems about to be determined a large number of yakuma appear and the battlefield descends into utter chaos.

With the sudden appearance of the yakuma, the recent great battle ended without a clear victor. While escaping into the woods, Yuzuki is injured and loses consciousness but is found by Kenshin Uesugi and taken back to his castle to receive treatment. Kenshin entrusts Yuzuki's care to his son, Kagekatsu but when her injury worsens Kagekatsu feels extremely responsible. It is during this time that information comes to light that the neighboring country is making suspicious movements so Kenshin decides to send a commander with reinforcements. He tries to task Kagekatsu with this mission, but having lost confidence in himself, Kagekatsu refuses and Yuzuki tries to get father and son to see eye-to-eye.
