Summary
"Acqua of the Back first version (left). I drew this around the release of Volume 13, so no "who is that?" jokes. When my image of the character is a bit vague, these kinds of changes are pretty common... On the right is my second version after getting feedback. The outer appearance changed a bit since I hadn't focused on it much for the first version. What stayed relatively the same was the "core" of my ideas such as having him look like a large man-eating feline such as a lion or a tiger and to have him definitely not be scrawny like Accel." ―Kiyotaka Haimura
