Some anime captivate viewers with dazzling fight scenes, while others leave a lasting impression through the stories they tell. “Blue Exorcist: The Blue Night Saga” falls firmly into the latter category. As someone who has followed Rin Okumura’s journey from the beginning, I found this arc to be the emotional payoff the series has been building toward for years. Rather than pushing the story forward with another battle against powerful demons, the fourth season of the anime looks to the past.
