Yukio is a skilled exorcist who is determined to protect his brother and the people around him from demonic threats. **

Yukio from Blue Exorcist is no longer a demon after the first season because he was able to resist the temptation of his demonic powers and maintain his humanity.

Additionally, his bond with his brother Rin and the support of his friends at True Cross Academy helped him overcome his demonic nature and stay true to his human side. **
