The friend of my friend is my enemy?!
Yukina is trapped in a pitched battle against Astarte the homunculus, and she's losing--when who should come to her rescue but the very boy she's been assigned to observe, Kojo Akatsuki! Akatsuki tries to end the clash, but Astarte's familiar, the fearsome Rhododactylos, isn't going to let that happen. Is this a fight that only an awakened Fourth Primogenitor can finish?
Kojou and Yukina join forces with Natsuki Minamiya to protect Itogami City from a new threat from the skies--but even Kojou's Beast Vassal can't take this new foe on, and who should rescue them from their predicament but Kojou's sister's friend, a silver-haired girl named Kanon Kanase! But when Kanon disappears, Kojou and Yukina may find that there are some problems not even the world's mightiest vampire can solve!
Kojou, having learned both the secret of Itogami Island and Eustach's true goals, agonizes over the right thing to do even as Eustach presses his attack on the keystone gate. Are the lives of the island's citizens more important than this strange new justice? Either way, their fate is in Kojou's hands!
Itogami Island is abuzz with preparations for the Halloween festival, and who should be visiting for the occasion but Kojou Akatsuki's friend from elementary school, a girl named Yuuma Tokoyogi. But as Kojou reunites with his friend, his homeroom teacher, Natsuki Minamiya, goes missing! Meanwhile, a strange space-time distortion is turning the sanctuary of Itogami Island into a labyrinth from which escape is impossible. And what's behind the physical changes that come over Kojou whenever he has physical contact with Yuuma? The long-awaited fourth volume of the light novel series is here!
Aya Tokoyogi and six other hardened magical criminals have broken out from imprisonment. Their goal--to completely erase the 'Witch of the Void,' Netsuke Minamaya, from existence. How these events will unfold in the Demon District will depend on the actions of the strongest vampire to ever exist, Kojou Akatsuki.
When all the students depart for a school field trip to the mainland, Kojou is delighted to hear that he'll finally get a chance to be free of observation for at least a little while, whereas Yukina has mixed feelings about the whole situation. But events move quickly when an alchemist by the name of Kou Amatsuka appears, with the goal of reviving the holy grail of alchemy--a liquid-metal life-form known as "Wiseman's Blood." As the crisis deepens, even Asagi becomes involved when this alchemist's relic grows more and more uncontrollable. What can the world's strongest vampire do?!
Yukina and Koujou are reunited once more and ready to take on the army of Nalakuvera! Will the strength of his new beast vassal allow the Fourth Primogenitor to reign supreme, or will the Black Death Emperor Front succeed in destroying Itogami City?
An alchemist repeatedly raids various places to get the liquid-metal lifeform--Wiseman's Blood. Blood spirals out of control in Strike the Blood's ninth manga volume!
