Deep in the night there is unequaled evil lurking about the streets of the city. An innocent hot woman wearing a kimono out for an evening stroll could be accosted by bands of roving Mimes who would annoy her to insanity with their evil annoying miming.
Fortunately for the sanity of mankind and the safety of innocent hot women wearing a kimono, Justice is here in its purest form: the Mysterious Unknown Ninja, Enemy of Crime and Corruption, Defender of Peace and Justice, Protector of the Weak and the Oppressed.
With a Ninja Protector coming to the rescue, innocent hot women wearing a kimono have nothing to fear from the insipidly annoying vile evil criminal miming of the lowly bands of roving Mimes.
Now you know. And knowing is half the battle.
