Manga made of Gurens Ichinose's Catastrophe at 16 item #640705
So far I've found 3 chapters online, not sure how many they're are in this volume but I'll probably buy it to find out (Hopefully they'll publish this in English along with Mikaelas Novel ><)
The art is by Azami You and not Yamamoto Yamato (who has illustrated pretty much everything up till now). From what I've seen the art does look good though.
