Rental Magica

Both series are about various stand-alone incidents related to supernatural events, and an organization composed of people from various religious/occult affiliations that work together. Though the views on how magic works and personalities of the character varies greatly, both shows have a lot a similarities. 

Both series is involved in mystery super natural&poltergeist.but i prefered ghost hound because they have great stories that make you want to keep wacthing,this is best horor series that i have seen comparing with other title had also super natural story spice .You will never regret if you watch this series. 

These animes have similar stories. They both fight demons/youkais with magic and they have Onmyoujis and shikigamis in common.for people who love with magic should watch this anime. 

-Both shows have supernatural powers. -Both MCs left eye is special and red. -Both situations have to deal with ghost or ghost-like creatures.  

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. 

Both Male MC share the same power of one of their eyes having the power to predict movements, though since they haven't mastered it, the effect only lasts for a few moments and MC suffers physical damage near said eye. Both dabble with different kinds of Magic (RM is supernatural phenomena while 11e is apocalypse-esque).
