this show was made to promote the light novel and focuses more on character interaction than the actual story so a 3rd season is unlikely because the purpose has been served yet still possible albeit a long way down the road
Does anyone know a rough analysis of when a season 3 may come?
everyone. the Creator (Akatsuki Natsume) said they will be no Season 3. but not for now, which means there could be a season 3 but not for now. because making another season would take time to make and to plan.
