With a grand and intriguing worldview of much potential of development, the series felt empty and wandering. Limited character development and weird motives raised questions during the viewing experience, which surely affected the overall picture. Devotion to shotacon and lolicon also stood in the way of the tone and character development. Still, the enchanting world of the abyss itself would be able to draw in many audience.
