Strike the Blood - Specials (2015)

A renewal of the non-aggression treaty between the Kingdom of Aldegyr and the Warlord's Empire is scheduled to be signed in the acceptably neutral Itogami City. King Lucas' misgivings about La Folia's relationship with the Fourth Progenitor result in him pressuring his daughter to quickly get engaged to someone. The Rihavein's host a large event that night and everyone is invited. Giant, flying, demon bugs crash the party and menace the attendees.

Lucas and Polifonia discuss the abduction with security. Meanwhile, with the two abductees bound and gagged nearby, erstwhile maid and now full-time terrorist Trine Harden discusses their plans while humiliating Kojo. The world is oblivous to the abduction which is kept from the public. On the day of the ceremony, at Trine's command, Kojo boards and takes over the Aldegyrian flagship, the Bifröst.

The Lion Agency and the Taishi Bureau have conducted a joint investigation on an unidentified marine accident occurring in the sea area around Itogami Island. On the other hand, Kojou wakes up after hearing a voice. The spectacle that jumped into his sight, whose memory was also dim, was a blanket and a cheek that seemed to have been wrapped and sleeping, cheeking, and Yukina's face appealing with tears. "Senpai ... I lost something important ...".
