At first, I must say that I want to examine this work logically. I don't know about the next episodes, just I'll write my views only up to ep4.
I follow this anime myself, but until episode 4, the story and characterization did not seem to reach a satisfactory level. Before examining the other strengths and weaknesses of the anime, I must say that this anime is at a very high level in terms of graphics, and if you are only looking for an anime with attractive graphic fights, see this work without reading other views.
But if storytelling and characterization are important to you, I don't think this anime can satisfy you much.
As I said, I follow the anime myself, but I think this work is unable to progress in the story because it is original, and it may be boring and repetitive.
Other weaknesses of the characterization that can be mentioned, the main character of this story and also the two girls next to him. For example, the main character's goals and feelings are very superficial and destiny's feelings are not understandable at all. The supporting characters of the story can not help the story as their place at all and look weak. The story may seem mysterious, but it leaves the viewer in only an aura of ambiguity, and the viewer cannot understand deeper into the ideals and goals of the main character. And the other thing that bothered me the most was the story villains. The story has not been able to address the D2s in any way. At least he could create creatures in these four episodes that would delight the viewer or create different types of these creatures, each of which has certain tangible abilities.
Finally, I must say that it is possible to develop the anime in terms of story, but what is characteristic is that this anime is still a work that has powerful graphics but is empty from the inside, and this work is famous only because of destiny's face and clothes and the graphics.
