Today's DVD/Blu-ray combo pack release will not feature OVA episodes
With the Senran Kagura anime series out in a DVD/Blu-ray combo pack today, distribution FUNimation posted a clarification about the release.
"We have recently been made aware of an error in listings for Senran Kagura: Ninja Flash! which stated that the release includes six OVA episodes. We do not have the rights to these extras, and they are not included on the release."
