Yuki Kaji:
"This is an opportunity! Don't miss it!! Everyone, let's change history together." "Soyogi Fractal" is a project I've dedicated my life to. For its first original work, I entrusted it to the one and only Hajime Isayama, whom I deeply respect. I'm sincerely grateful to Isayama for accepting this request.​

Hajime Isayama:
"I participated in this project at Kaji-san's invitation. It's been about ten years since I've worked on a manga outside of 'Attack on Titan,' and I've once again realized how challenging manga creation is. However, since I'm not doing the actual drawing, I can create as many complex compositions as I like and leave the rest to others—it's fantastic."
