While we know that FUNimation has picked up the streaming rights for a number of series, they don’t always pick up both the streaming rights and the home release rights at the same time. That is why this weekend FUNimation has announced that they have picked up the home release rights to bring The Devil is a Part-Timer!, Senran Kagura, and Hetalia The Beautiful World to North America on DVD and Blu-ray, though Hetalia will only be getting a DVD release.
At the moment the company has not announced any release dates for these series though we can likely expect them sometime later in 2014 or early 2015.
