Strike the Blood FINAL really is the end of this vampire line

Strike the Blood is a series about the fourth progenitor, a vampire so powerful he was once thought only to be a legend and the girl sent to watch and, if needed, slay him.

The series had a 24-episode run in 2013 and then multiple OVA seasons after that, then some more. OVA episodes, original video animations, aren’t always intended for broadcast, so they have more liberal censorship and are sometimes separate or additional to the main story.

Strike the Blood FINAL is the fifth extra bit of story, as it uses up the last of Gakuto Mikumo’s light novel content.

This trailer for Strike the Blood introduces a new character, Shafrial Ren’s younger sister and a team leader. The discs will ship on March 30 and then the second half of the four-episode bundle on June 29. Like some other OVAs, the set is intended to be collectable and has bonus material.

Yen Press has the rights to the manga English language, which is sold on ComiXology. They describe the series;

Kojou Akatsuki lives on the artificial island of Itogami, and he has a secret: He’s the “Fourth Primogenitor,” the most powerful vampire in the world. He’s carefully kept this dark knowledge from his family and friends, but one day, a beautiful girl named Yukina Himeragi appears before him and tells him that she knows who he really is–and that she’s been sent to…kill him?!

Crunchyroll has the rights to show Strike the Blood and to prove that OVA sometimes make it to streaming platforms, there’s also the Strike the Blood OVA bundle there. It’s not known if FINAL will make it to the system.
