I do miss Guy sensei :'(. At this point Cody has a much higher chance of being in than Guy does. Especially with the inclusion of Zeku/young Zeku and Cody being waaay more popular than Guy.
Yeah. Some people think that's his student and some think thats a young version of him. From what I've heard Zeku is called the "ever changing ninja" so I guess that actually is Zeku as his young self.
They are setting Zeku up to be a Ibuki's pimp. All jokes aside, Im still wondering why he has a young guy with him. Some people think he's Zeku in a transformed state while others think he's Zeku's new tag partner/student.
