I'm a Kanzaki Yuuya fanboy, and I love this kind of premise. I hope you enjoy it, too!
By the way, to elaborate a little more on what I said in the series presentation…
This was supposed to be a first chapter with 60 pages and a colour double. The title of the chapter was an introduction of the two main characters: "Saitō Yu'ichi and Mitsumune Sakutarō". That's what it says in the colour double. For some reason, though, the double was scratched and the debut was demoted to a 26-page chapter called simply "Prologue". Maybe Kanzaki didn't make the deadline and they had to improvise, or maybe there wasn't room in the magazine for 60 pages. (It ran in the same edition as the final chapter of BTOOOM!, by the way.)
