The bottom line is that we have accumulated in my head thoughts and information. When the head is full,all the excess is converted and as a result a kind of parallel world, in this case - is Umer, a country of dreams, which was created by the protagonist of the series. And in every dream has its nightmares, their accumulation forms Feyduma, antagonist of our hero. The problem is that Feydum can get into the real world and make an apocalypse.To avoid this, Mikura and kawaii team (which he accidentally pulled into the world of dreams) consistently kill the henchmen of the main villain (any cubes Rubik`s eyes, they reminded me of the enemies in the game " Galaksion "), well, the last and the main villain. It`s pretty simple, no philosophy here and does not smell.
