This is a wonderful series, i re watched it recently in BD and it is superb..it has all the fine qualities that good anime has, great story, wonderful art and character design and a really heartwarming and enjoyable overall feel to it. It is a theme that has become more popular recently, with variations, and this is one of the best. I do hope they will continue it, from the looks of the second OVA it certainly looks like they hope to. We see a new character introduced just landing in Japan, and I am certainly ready for more of this wonderful story. I am so glad we get such fine anime continuing to be developed.
And in support of posts above, no there is no censorship in the BD version as always., Well worth looking for, even tho this is no hyper Ecchi series, it has a very nice side of that to it, with both the main girls. Such a nice range here and so well done.
Hoping for more soon.
