The story progression was messed up, and the plot was all over the place.
Could have had this run for a few more episodes to bring the story together.
The MC especially Erika and Kouhei needed more substance and character development.
The theme was well picked up, on vampires and the school setting was great but depth in each character was major missing.
Introducing a rivalry for Sendou could have had maybe a better impact on the storyline.
In the end, the anime leave the viewers with mixed feelings, and sadly the anime did not get another season, now we know why.
