That's right! This technically the "last" episode of Dirty Pair! ...or at least the last one to air on TV. The final two episodes of the show would end up being the first two examples of a Dirty Pair OVA, which we'll obviously be seeing more of in the immediate future.
In the meantime, go look at Kei's outfit in this episode: a tan girl with wild red hair running around barefoot in a shoulder-less yellow/white top and blakc shorts... is this what Radical Edward is gonna look like all grown up?
