Matantei Loki Ragnarok, Rental Magica Recommendations
Extremely similar concepts. Both the series has their own plotline, but follow a monster-of-the-week format (meaning that almost each episode is self-contained) although an ongoing plot often involving the main character is present. Magic, spirits and the like are also present when it comes to the different characters in both of these series combating the antagonists.
One cannot simply dismiss the similarity in concepts between these titles. While watching Loki, I cannot help but remember Rental Magica from 2 years back and definitely Neuro. Sharing a concept which involves some form of western occult magic, for instance, Rental Magica embraces all forms of world magic folklore such as Celtic, Solomon and Japanese Onmyouji, while Loki focuses on Norse mythology, as observed by the main character, Loki, himself. Additionally, the gradual and slow pace of plots between the two shows are observed in a similar fashion for both titles, which thus brings out the development and characterisation of the characters effectively.
