Re:Zero fans rejoice, because the anime is getting a second OVA! The anime’s official website has updated to reveal the second OVA, which is slated for an autumn 2019 debut. They also revealed a teaser visual for this new anime as well:
It will only have one episode, and its title is “Hyouketsu no Kizuna” (Frozen Bonds). It will be a prequel of sorts, following the story of how Emilia met Puck. This will also be the second OVA, for the Re:Zero, with the first one being Memory Snow.
The OVA adapts the Re:Zero Kara Hajimeru Zenjitsu-tan: Hyouketsu no Kizuna prequel novel, which came bundled with the anime’s first volume Blu-ray release.
