As this manga was made to commemorate the Dark Side of Dimensions movie, this work didn't expanded the lore or gave a good prologue for the movie. Heck, it didn't even presented itself as informative and satisfying, though it was a bit interesting for a potential reader to check it out. Sure, it gave out a sneak peek of the main antagonist and their motive (well, not really their primary motive), but honestly it felt lacking. Yes, this manga is lacking in plot and character development, though the art improved a bit. After reading the 343-chapter manga (or watching the 224-episode anime), might as well gostraight to the Dark Side of Dimensions movie. As this manga is only 2 chapters it can be skipped, as the main plot continuation is in the movie. This can also be given a try because why not? It's only 2 chapters and a very short time is only wasted.
