Op: Yoake Itaru no Iro no Nai Hibi

A 38-year-old divorced man works as an investigator and confidential informant for an insurance company, handling cases that others avoid. Each day, he encounters incidents that appear to be accidents but are often disguised as suicides or murders. Those involved typically turn to him for assistance. His days remain monotonous and devoid of color as he continues this work.
