Episode 3 which is also the last episode, is scheduled to be aired on 4th April 23:00 JST at Tokyo MX channel. I expect Crunchyroll is going to simulcast it shortly afterward just like the first 2 episodes.

There will be 2 DVD only episodes, 1 episode for each DVD and both of them are side story. The 1st one features Hero Myumuto and the 2nd one features Crystal.

Too bad this adaptation only covered the 1st arc of the web manga.
Episode 1-3 on the DVD seems to be uncut version, I wonder what they mean by the uncut... Is it only removing the censors from censored scenes or there are also some scenes which are being cut in the TV airing...
