The official website for Valkyria Chronicles 3 has recently updated itself with a trailer of the upcoming 2-episodes OVA series for Valkyria Chronicles 3. It has been quite sometime since we last saw any animation regarding Valkyria Chronicles!
As you have guessed, since Valkyria Chronicles 3 focuses on the 422th Squad called the “Nameless” squad, the OVA will be focusing on them, although other characters from VC1 still makes an appearance in the OVA series.
The first episode of the OVA series will be released on 29th of June. No word on the release date for the second episode.
