The series will keep having an OVA format and will not be broadcast on television like the first season was. This is due to the poor ratings the first season received in Japan, and companies are not willing to allot for 13-episode seasons when the format is 26 episodes per season. :(This was all according to a TMS Entertainment spokesman at the "XVI Salón del Manga" convention in Barcelona, Spain.
The second season will premiere on February of next year and it will be a straight to DVD/BD release.
Quite a mixed bag, isn't it?
