“No Senpai, these are my pantsu…”
During the Dengeki Game Festival 2015 event it was announced that Strike the Blood will be receiving a two-episode OVA series scheduled to be released at the end of 2015. The OVA will be an original story written by Gakuto Mikumo.
A promotional video was also previewed at the event:
The rest of the video with part of the cast attending the event also promoting a new drama CD, which I believe was semi-broadcast on NicoNico, all in Japanese:
The original 24-episode television anime adaptation by Silver Link and Connect aired between October 4, 2013 and March 28, 2014 in Japan. The 1st half of the series had a lot of teasing shots with the closest full nude shot by Yukina for a nipple slip, define more on BD, and plenty of pantsu, fog/light censored and butt shots from the rest of the cast. The 2nd half finally delivered with Asagi breaking the nude wall followed-up by Yukina in the last part of the series.
The series only covered about 6 volumes + 1 side story out of currently 12 volumes so hopefully a 2nd series is announced at the end of the 2nd OVA episode and we can get a shot at the rest of the cast, particularly for me Sayaka and La Folia Rihavein.
