Abel is Denzel's father in On the Way to a Smile "Episode: Denzel". Abel worked in Shinra's Third Business Department and lived above the Sector 7 plate. He is voiced by Yoshimitsu Shimoyama in the OVA.
Having been born in a poor village, Abel was proud to have come so far and, believing it was important to maintain a goal in life, hoped to one day move his family into Sector 3. As Denzel's flashback begins in the novella, Abel is promoted to the head of the department and makes plans to move to Sector 5. Abel told Denzel that the people in the Slums below the plate ate rats and that he was lucky to be born above the plate.
On the day that Shinra destroyed Sector 7, Abel searches for his wife Chloe, but cannot find her. In desperation, he takes Denzel to Mr. Arkham and has him take Denzel to their Sector 5 home. Abel remains behind to find Chloe, and they are both killed when the plate falls.
Abel is the second son of Adam and Eve according to the Book of Genesis. When Abel and his brother Cain both made offerings to God, God accepted Abel's offering over Cain's. Jealous and angry, Cain killed his brother, becoming the first murderer.
