The plus points: definitely the animation for the fight scenes as well as the emotional impact during the climax of the OVA. Without knowing much of the source material, the way we are given a rundown of the characters and how they react to the situations had depth. I do feel like more could've been done to give us a better look of the connections between Raizel and Muzaka. Either way, the premise is intriguing for me so I will definitely check this series further!
