Summary
"The cover for New Testament 3. Mikoto is wearing her alternate outfit I had uploaded to pixiv before (and put in my art collection). (By the way, Hamazura is in his alternate outfit as well. Accel-san's outfit seemed it would leave him too hot, so I gave him something else to wear.) When it came up that I had to draw new Hawaii outfits for them, I suddenly remembered I had those outfits. Not only did it reduce the work I had to do, but it also would have been a shame for those outfits to have that one illustration and never be used again. I guess this was just perfect timing." ― Haimura Kiyotaka
