Here's the PV of the 4th OVA of Attack on Titan, which is based on the canon spin-off "No Regrets", brought to you by Saizen and Soldado-Subs. Note: This is a webrip from Kadokawa's YouTube page. So the quality won't be as good as it can be. There will not be a 720p version, sadly. But feel free to download the video from their page and use our subs if you can't play it back for some reason.
