This is, arguably, different from most types of anime and manga that I do watch -- which tend to be more on the side of either mecha, heavy back-stabbing politics and assassinations, and dark/horror stories.
That being said, I couldn't help but find myself very vested in the main character.
Raised by Father Fujimoto, a famous exorcist, Rin Okumura never knew his real father. One day a fateful argument with Father Fujimoto forces Rin to face a terrible truth – the blood of the demon lord Satan runs in Rin’s veins! Rin swears to defeat Satan, but doing that means entering the mysterious True Cross Academy and becoming an exorcist himself. Can Rin fight demons and keep his infernal bloodline a secret? It won't be easy, especially when drawing his father’s sword releases the demonic power within him!
The main character, Rin Okumura, is your typical bratty teenager at the start of Volume 1.
After a rather nasty argument with his adoptive father ( who is the strongest Exoricst of his time ), Fujimoto's strong will weakens JUST enough for Satan to posses him.
Satan, being strong, begins to decay the body of Fujimoto right in front of Rin's eyes, revealing that Rin is in fact Satan's son -- and to embrace his true, dark nature.
Rin himself goes through some amazing changes through the course of nine volumes. Life forces him to grow up -- quickly.
Even more so, because he is Satan's son, his power is often wild and uncontrollable. His flame has been shown to threaten the lives of his adoptive-brother and friends alike.
His interactions with everyone over the course of the volumes just gets better and better. There's a few "low" points, but otherwise the story is absolutely amazing.
Rin's brother, Yukio Okumura, is a well-established Exorcist in his own right, also has some good interactions throughout the story -- but really, Rin steals most of the show.
And then there's Mephisto.
Mephisto is the ambiguous character in this series. He's a demon -- and not just any normal demon, but the second strongest of the Eight Demon Kings, just below his brother Lucifer. He is also an Exorcist, and runs an Exorcist School. At times, he can be seen helping Rin from behind the shadows, but it's hard to say what his goal is -- is he helping Rin grow stronger for the friendship he had with Fujimoto, or is he doing this advance Satan's cause?
Summary : 4 / 5.
Recommended : Anyone who likes good characterization, manga/anime in general, or demon-exorcist based stories!
