This anime is...decent. I am trying hard to see how this book was able to produce not only more sequels, but was able to spawn a whole franchise that created such games like Persona 3 and Cathrine. Maybe there was more to the book, but everything here just felt dull and average.
The art was ok, sound ok, the end song was typical 80s cheese, and there was a lot of blood. But after the beginning where we see Loki summoned? That was when it just felt dull and lifeless, like the anime wanted to get to certain points as fast as it can with little care for the characters and stories.
