This is an anime that doesn't have any clear direction. It felt rushed and had little development throughout the story.
Story 5/10- The story didn't flow very well. Events happened that didn't seem to fit the flow, random new injections occurred all the time leaving the viewer to question what they should be paying attention to.
Art 7/10- The characters looked fine, however, they didn't have the most detail. Colors were used wisely to fit the mood the creators were trying to get at. But the Gastrea looked really weird and failed to impress to me.
Sound 8/10- The soundtrack was done very well.
Character 4/10- The characters
were all very predictable and 2 dimensional. But if they weren't following a predictable pattern they were acting in ways that made no sense. Lots of Lolis who wanted MC detracting from me caring about anything else they said. New characters were introduced and given screen time only to play a minimal inconsequential role with no follow up.
Enjoyment 5/10- The fight sequences were pretty cool, short but well done. The art and soundtrack were well done. But the story was choppy and left me wondering if anything covered in a certain episode was even important. Characters were poorly done and left me with no emotional attachment to any of them. And the ending was all over the place. It went from predictable, to what Hell is happening?
Overall- If you like Loli harem this is the anime for you.
