|Name Kanji||アベル, Aberu|
|Anime Debut||Episode 9 Ninth Coffin|
He lived along side his brother Cain and was a beloved member of their community until he was murdered out of sheer jealousy by his own brother. After death, Abel rose as a Shiki and followed his murderer wherever he went after the latter's banishment into the wasteland. For a time, his brother believes that Abel followed after him in order to exact some sort of revenge. Fed up, Cain finally confronts Abel and asks why he follows him, even after death. The younger admits that he wanted to be killed, and thanks his brother for his deed. Abel had hated his life in the village when he was forced to act as a cheerful person who was beloved by many, and wished for some sort of escape. He then fades away, never to be seen again.
Abel was stabbed in the face with a pitchfork, which was wielded by his brother Cain.
- He is based on Abel from the Judeo-Christian Bible, who was also killed by his brother Cain out of jealousy for being favored by God.
- According to Seishin, Able and Cain were the same person and had become one.
- From what Muroi had said, it appears that Cain/Abel committed suicide, which seems to mirror Seishin himself as he attempted to take his own life in the past.
