After the conclusion of Akio's first boxing match, and the shocking defeat of the man known as "The Devil", Akio prepares for his second match, though that proves to be no easy task. In a small, run-down house, which they call their base of operations, Akio and Dr. Arrow prepare themselves for Akio's second match, while also tracking down Jett.
Meanwhile, to their luck, those who were able to escape with the help of the doctor are apparently still alive, though Jett was actively looking for them, according to him. After they tracked them down and had them join their alliance, though, Akio's training became harsher.
Dr. Arrow and his men developed special robots that look like Jett and had supposedly the same power as Akio when using his Resonance, after some studies on him and his magic, though Akio seems to be taking this training a little too seriously.
