This will be the second OVA series, after a 2-part OVA series was released last year.
A wrap-around jacket on Vol. 15 of Gakuto Mikumo’s Strike the Blood light novel series has revealed that the fourth progenitor and his kill-stealing, spear-wielding kouhai are back for a second series of OVAs.
Not much information, such as how many episodes for the new series, has been revealed for the new OVAs, so stay tuned for more announcements.
