Review Detail of Alex3DxD in Mark of the Multiversal Pretender

It is seen that he put effort into the work and that is why he fails. The introduction (chapter 20) is very slow, it is summarized in training to obey the system and some talks that are not interesting at all, he obtains the ability to travel between worlds and returns to train again, now being an extra behind the protagonist. . You give a lot of weight to the boring plots and the system, it basically carries the entire plot.
