I was watching Blue Exorcist and this idea popped into my head. I was really curious as to how he dealt with knowing he is the Son of Satan. Enjoy!
The Final Designation
Rin sat in his dorm room, attempting to do his Biochemistry homework. True Cross Academy required all students, even Exorcists in training, to study the basics. Rin hated it because he felt he wasn't learning anything important. Yukio told him that it was essential for him to learn as much as he can before he goes off to kill Satan. Still, Rin enjoyed complaining.
"Stupid chemicals," Rin muttered as he turned the page. He groaned when he saw a list of chemicals and other big words that he couldn't pronounce. He slammed the book shut and threw it to the other side of the room. It slammed into the wall above Yukio's bed and felt onto the white linens.
"Yukio, I still can't see the point," he sighed. He laid back onto the bed and looked at the dull white ceiling. He stretched his legs out and his foot hit something hard. He looked down and saw his sword, Kurikara. He reached down and grabbed the blade. He ran his hand over the hilt.
I am the Son of Satan. I am a demon…
He gripped the hilt and gritted his teeth. Why?
Rin laid back onto the bed and his mind drifted into dark thoughts. His eyes found a piece of paper taped onto the wall above his desk. It read: "Blessed are those who follow the Lord. He will give thee rest."
Rin scoffed. "Why give salvation to the kid of Satan."
Ever since Rin found out that he was the child of Satan, he had begun to question things he had never thought about before. He had been raised in a monastery, but he had never considered his soul, and the afterlife. He remembered his father, Shiro, telling him and his brother that Heaven was waiting for them, as was their mother. Rin never listened to his words, but now the echoed in his mind.
Was there really an afterlife? Was there a Heaven and a Hell? It was obvious that demons and Satan existed, but was there a place for the soul of those in Assiah? Where would he go?
He had no answer. He remembered hearing those who accept God go to Heaven and those who do not accept Christ go to Hell. He was never really sure it he believed it or not. He believed in Gehenna and Assiah, of course, but that was about it.
He was the son of the vilest. Did he still have a soul? Did he lose his soul after he used his flames? Did he curse himself or was he already cursed from birth?
Rin turned over to his side and clutched his sword, a feeling of emptiness in his heart.
Will I fly or burn?
