The Biglobe video-streaming website has posted a promotional video for the Kodomo no Jikan Second Term original video anime (OVA) series. (Microsoft Internet Explorer 6 or higher is required to play the video.) The site also has a video message from the voice actresses Eri Kitamura (Rin Kokonoe), Kei Shindou as (Kuro Kagami), and Mai Kadowaki (Mimi Usa). The anime will begin with a preview episode bundled with the sixth volume of Kaworu Watashiya's original manga on January 21 in Japan.

The new anime series will follow after the story of the Kodomo no Jikan television series and cover the elementary schoolgirl characters' time in fourth grade. The actual video series will launch with its first 55-minute volume on February 20. The anime's official website announced that it would stream the opening and ending animation footage last week, but the footage may not be accessible outside Japan.
