With Season 3 over now i'll have to give out the usual announcement. Please refrain from asking when will Season 4 come out. No official confirmation has been given, so please wait till an official confirmation is released. Failure to abide to this rule will result in a 1 day ban for the first time and will be longer subsequently.
Finally to appeased all those that keep on asking
There'll be an OVA released on December 2015. Any news of Season 4 might be released then, so please refrain from asking about season 4.
Thank you for your assistance. Viva Oppai!
