Summary
"Now for the Volume 10 cover. Simply put, this is the “opposite” of Volume 9, so I considered having Kamijou on his own, but I decided to have him protecting Othinus to directly connect to the double-page spread at the end of Volume 9. There’s also the fact that a guy-only cover is extremely difficult to put out for a male-oriented light novel, but with the precedent of Volume 15 and 19 that may not have had much to do with this decision."―Haimura Kiyotaka
