A four-episode original video animation (OVA) series, animated by Brain's Base and distributed by Bandai Visual, was released between December 21, 2007 and December 19, 2008 on DVD in regular and limited editions. The limited editions contained a bonus CD soundtrack with each DVD and a different cover artwork. The story of the OVAs follows Haruka's route, in contrast to the TV series' modified version of Mitsuki's route. Haruka Suzumiya awakens after a three-year coma. Time has deprived her of many important things, but one still remains: her love for Takayuki Narumi. They visit various places they remember, as if to recover the time that was lost. However, there is one place they refuse to visit: the phone booth in front of the Hiiragi-cho station, where Haruka had her accident three years ago.
