@Deshter, You'll be pleased to know that both are printed in the same manga publication, Harta.
Also here's an old image when vol.2 was announced, it was in comic zin's front window at akihabara;

I bumped into this manga somehow and was really fascinated.
It seems Vol. 2 is released and the first chapter is translated already, so will we see another several chapters soon?
