Finished it (but really I want to read the whole series ;_;), gosh I dunno if I should be happy or sad. The ending did say their "everlasting connection". It's a pretty cool manga!
I had all four volumes when they were first released, but the English translation company went under before releasing the final volume. I was so relieved to find it years later. But I saw that she supposedly wrote a follow up to this manga, so I'm wondering if I'll ever be able to find it. Here's hoping someone translates it, though I'm almost afraid to see what a continuation would look like, considering the fact that this is a happy ending as far as the mangaka's usual stuff goes.
So.. Chapters 1-19? Or is it another story entirely? Oh I'll check it later, this looks really good.
