Kei and Yuri are the two members of Trouble Consultant team 234, code named "Lovely Angels". Almost every mission they are involved with ends up in disaster, though not failure: They typically capture their target fugitive, but end up destroying a city in the process, earning the nickname the "Dirty Pair", a moniker they openly hate being called. They are always cleared of any wrongdoing by the 3WA's Central Computer because the extreme collateral damage is never actually determined to be their fault, although their mere presence tends to worsen the situations for which they are hired. In some but not all continuities, they have joint extrasensory perception powers, usually limited to precognition. This talent was the reason they were recruited in the first place.
Dirty Pair (1985) is currently not available on any services.
