Summary
"The Volume 21 cover rough. Displaying something from the end of the novel is fairly rare. Normally, I try to avoid spoilers on the cover as much as possible. I also had the idea of showing Mugino's expression clearly, but I felt it would be fun to draw her like the "mysterious enemies" from a Kurumada manga (even if it was plain as day who it was)." ― Haimura Kiyotaka
