A short review would be this
Comedy and martial arts meet in this crowd-pleasing Korean manga.
Bi-Kwang is a handsome young warrior who becomes a drooling mess whenever he sees a pretty girl. Out on the road he meets an extraordinary sword fighter with no name who is searching for a legendary master warrior. Bi-Kwang promises to aid the swordfighter if he lets Bi-Kwang meet his beautiful sister. Of course, it turns out the sword fighter is the sister, Hwa-Rin Dahm, and she must switch identities to keep the plot moving along. Bi-Kwang is immediately smitten, and thus we have a triangle involving only two people. Yet another manga that uses cross-dressing as a plot device, Ruler has the wit to poke fun at the absurdity of the convention: Hwa-Rin is astounded by Bi-Kwang's stupidity in being fooled by her masquerade. Indeed, Bi-Kwang goes to unbelievable but funny lengths to explain away every piece of evidence that the "swordsman" is a woman. This unlikely pair is hunted by many enemies, although the greatest danger to Bi-Kwang is probably getting beaten up for taking liberties with the ladies.
