The TV anime produced by A-1 Pictures was aired for two seasons in Japan: 25-episode first season (April-September 2007) and 13-episode second season (April-June 2010).
Aniplex has revealed its jacket illustration newly drawn by the anime character designer Takahiko Yoshida (Yowamushi Pedal anime series).
The 34,560-yen (about 303 US dollars) box set contains the 38 episodes of the two seasons with two extra episodes: the first season’s 26th episode “Kihon no Kihon” and the second season’s 12.5th episode “Mokuhyou.”
