Odile is a private investigator who runs a PI office in Demon World.
Formerly a detective at the Demon World Police Department, she used to be a role model for her fellow officers for her excellent focus and ability to find evidence. She was even awarded a certificate of commendation by the central government for dramatically increasing crime arrest rates.
After leaving the police force and temporarily living a life of debauchery, Odile set out to pursue a new career. After much deliberation, she decided to become a private investigator where she could utilize her investigative skills. Odile spent all her money to set up a small office and began searching for a partner to work with. That is when she meets 'Gremory' again by chance, a five-time convicted felon whom she once met at the police department. Although Gremory was an ex-convict, Odile remembered how helpful Gremory was with her investigations and offered her the chance to become partners. Gremory willingly accepted under the condition that Odile funds her research. They later named the office "O&G PI Office" after their initials.
However, the PI business wasn't as smooth sailing as they had hoped. While they had a steady stream of work, they were mostly errands like finding missing pet monsters or searching for evidence of affairs. This was hardly enough for Odile, who wanted to take on bigger cases. On top of that, between office rent and covering the cost of repairing the vandalism caused by Gremory's research, Odile was always short of funds. Thus, Odile often goes on business trips to places even outside of Demon World.
Though Odile is constantly tired from non-stop work, she feels rewarded when she sees how happy people are after their case is solved and when they thank her for it. Whether it's a major or minor request, she always takes on a great deal of responsibility to help people solve their problems.
