Yeah but like, if you don't know who either character is or what their motivations are after Donald duck and goofy the dog basically look into the camera and explain it to you, i'll think you an issue processing shit.
The series is bafflingly, hilariously distinguished mentally-challenged, in the way that only the goofiest of Shonen anime are. But that's all it is, is a dumb action anime where everyone wants to become strong by fighting over the Heart mcGuffin, and it asspulls because it has to write it's way around a villain losing eight consecutive times.
I'm not saying it's anywhere near good writing, but it's really really dumb and simple on a game by game basis. It only sounds complex in the same way that summarizing the last ten years of spider-man or batman comics, or all of LOST would be. It's volume.
