This post is about Rin Okumura from the show Blue Exorcist. Rin is the son of Satan, and the older twin brother of Yukio Okumura. Rin is 15 years old, and he is the one who inherited his father's powers, since Yukio was too weak. He didn't have his demonic powers at first, but he gained them when he pulled out the sword called the Kurikara, which is where his powers had been sealed away. Now when he pulls the sword out of it's sheath, he is covered with blue flames, and his teeth and ears grow to a point. He also gains a tail. He is determined to destroy his father, and he wants to become an Exorcist so he can do so. He has somewhat of a temper, and he is also a very good cook.
