Oscar Dressel

Oscar Dressel or known with his nickname The Ripper or Demon Slasher, is a demon hidden within the police force and the older brother of Fugo Dressel.

After he was defeated by Noel and Caron, he defected to their side to take revenge on Burrows. His official demon title is Demon of Justice.

~!Oscar was born and lived with in LaPlace with his parents and younger brother, Fugo. When he was a child, he has sickly body, spending most of his times bedridden in the hospital. Despite his condition, he was still happy with his life thanks to his family's encouraging presence. His younger brother, in particular, visited him at the hospital everyday.

Oscar eventually got better and was allowed to leave the hospital. Tragically, not long afterwards, his house was burned down after it got into a crossfire caused by Burrows and Jino, which was reported as the aftermath of a fight against a demon or devil. Oscar survived the fire, but his parents were killed and his younger brother went missing. Orphaned, Oscar was neglected by his relatives who all refused to take him in until Jino came and took him to his custody.

Traumatised by the incident, Oscar decided to attend police academy to become a police officer in hope of finding his missing brother and save as many people from terrors caused by demons and devils in LaPlace.

During an operation to catch a demon known as Bomber who terrorised LaPlace with his bombings activities, Oscar was appointed to take the lead of the capture, cornering the Bomber. To his shock and horror, Oscar found that the Bomber was none other than his missing younger brother who became fascinated by the power of demon after the fire that burned down their home. With Fugo refusing to let go of his demonic power and surrender, Oscar determined to defeat Fugo so he can take him back to the right path. Unfortunately, Oscar and his forces were not strong enough against Fugo's power as a demon, resulting in their defeat.

Oscar's determination to take back Fugo at any cost led him to request Jino to introduce him to a devil so he can make a contract and become a demon, believing that he can defeat his younger brother if he has the same demon power as him. Oscar trained his new demon power while keeping it a secret from the police force since making a contract with a devil is against the law. Oscar became strong enough that he was capable of entering the state of Fallen Down at any time by his own will. His records in stopping and capturing demons and devils earned him the title of Demon Slasher or the Ripper.!~
