KFM and Suave Dude are brothers. Their father was a renown Gunsmith, while their mother was a renown Martial Artist.
needless to say, Philosophical issues drove the family to split: KFM stayed with the mother, while Suave dude stayed with the Father.
Years later, Their father died. however, to truly inherit his father's spoil, Suave dude needed the second of 2 twin guns that his father made. He gave one to him, which is the one he uses, and the other was given to KFM.
Only KFM and his mother knows where the other gun is (KFM never used since, like his mother, he believes on the power of the palm and feet rather then bullets), however their mother is MIA.
Since KFM is the only with the location of the other gun, Suave dude Kidnaps his girlfriend. the quest begins.
Spoiler: KFM's true ending (click to see content)
After countless of battles, KFM finally founds Suave dude on the last of all places: Their family ancient mansion. after a fierce battle against Suave Dude, in which KFM loses his right eye, KFM discovers that his "girlfriend" is now his "Sister-in-law". She had married Suave dude during this time.
After this severe moral blow, KFM, with a deep felling of having lost, returns to the mountain side temple, which is revealed to be the place where KFM lived with his mother, before she went missing
Suave dude, who had planted microphones and cameras on the temple, starts spying on KFM, to see if in his sorrow, he would reveal the location of the other gun. however, due to a faulty system bought on a used computer shop, the cameras actually take several minutes to turn on. all that Suave dude hears is a gunshot, and when the cameras are ready, SD sees KFM's body, lying down.
suave dude goes to the temple, where he checks the body. believing that the body is truly the body of KFM, he goes insane. He reveal to his wife that the marriage was part of his plan to get the other gun, and shoots her. she dies as "KFM's cheating girlfriend".
without the location of the gun, and without the inheritance, which will be transfered to a Charity fund that teaches martial arts to kids, Suave dude Kills himself.
On the last scene, an One-eyed KFM appears. he confirms the fate of everyone, including his clone. under Suave Dude's body, he opens a small shaft, and takes a transparent box, with a gun in it. he takes SD's gun and put it inside the box, and start walking towards sunset.
his final comment is: Now to deal with mama...
edit: it might be weird that KFM used to live on "Suave Dude's secret mountain temple hideout" as stated in the intro, however, that place only started to be SD's hideout after KFM left (which is after their mother went missing). Also, this explains how KFM knew to look for SD there.
