Shiro Fujimoto
One of the characters in the manga/anime series Blue Exorcist and one of the best anime father characters is Shiro Fujimoto. He raised Yukio and Rin Okumura as his adoptive children. After becoming possessed by Satan, Shiro regained control of his body, killed himself with a knife, and shielded Rin from Satan.
He is renowned for having unmatched exorcist abilities. At True Cross Academy, Shiro is a Paladin, an honorable designation. He was cruel and impolite before meeting Rin and Yuki's mother, Yuri Egin, who transformed him. He took over and made the decision to raise Yuri's children as his own after she passed away. Even when Rin made crude and juvenile remarks, Shiro never gave up on him. In order to keep his kids safe, Shiro gave his life when Satan gained control of him. He truly is the epitome of a devoted father.
Shiro Fujimoto has a protective nature and a good heart, despite her mystery. Despite being a Paladin, he is not ruthless when it comes to Demons because he is friends with Kuro, a cat sith, and is Rin's adoptive father, making him one of the few individuals who can soothe Rin. He claims he injured his ribs so a busty nurse could take care of him, yet despite being a priest, he can be childish, joke about, and like ladies with large breasts. He may have passed on some of his personality traits to Rin and possibly Shura.
