Blue Exorcist

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!

Answer 2

One anime where the main character goes insane and shows their true abilities is "Death Note." In this anime, the main character, Light Yagami, is a brilliant high school student who becomes obsessed with using a supernatural notebook to rid the world of evil. As he uses the Death Note to kill more and more people, he becomes increasingly ruthless and begins to see himself as a god-like figure. His sanity begins to unravel as he becomes consumed by his own power and belief in his own righteousness. As his mental state deteriorates, he becomes increasingly reckless and violent, eventually revealing his true abilities as a master manipulator and strategist. The anime follows Light's descent into madness as he tries to outsmart the other characters and maintain his grip on the Death Note.
