Given the fact that they seem to have axed it, the ending was quite nice. It's still really sad that it didn't get another volume which it certainly would have deserved.
@SleepyAbra: The next volume seems to continue with Yuki, the "blonde" girl Rina and the guy she meets on the last page(s) of this chapter. But there's not much out yet as far as I can tell.
Wow, this is literally the one worst kind of licensing I've seen until now. No paper/digital release, monthly subscription only, IOS only and partly region blocked... fml.
@Abedeus: Over here in europe it's ~12€ for the print and ~6€ for the digital version. So it's indeed more expensive as print, but that's what you'd expect in a foreign, small market.
