Where can I read Mahou to Skytube de Ikiteiku?


I found _Mahou to Skytube de Ikiteiku_ by accident at some point not that long
ago and tried to look for it everywhere, even on illegal websites (though I'd
much prefer a physical copy). However, I can't seem to find much about it.

Where can I legally obtain a physical copy, or failing that, where can I
legally read it online?
