I anticipate action after all this supspense
This animation is very clean and the voice acting is very clean.I really wanted to give this a 10 when I first started watching... However, something about this animation feels cheep. The whole flash seemed like one giant interruption after another. The two settings you were changing between don't appear to have much in common to a new view like me. If showing both plotlines I suggest only changing setting only once in a short animation like this... The action to suspense ratio feels closer to a movie trailer than an actual movie.
I also think introducing new characters to the battle scene without letting the current characters fight it out a bit more takes away from the story, The battle scene seemed more of an introduction to the villain and competing heroes than a battle scene.
This is great except for how broken up the story is.
