In Seoul, the masters of the secret disciplines of the East are preserving the peace of our world without our knowledge. Sang-hwan became a cop out of his naïve desire to bring justice to those who are taken unfair advantage of. But the reality is that even local gangsters can beat him up. One day, he encounters the Seven Masters, who tell him that he is destined to become Maruchi. They teach him how to shoot ch’i energy from his palms so that he is prepared to work with his partner-to-be, Eui-jin, who is destined to become Arachi. Sang-hwan of course thinks they’re pulling his leg, but Eui-jin is cute, so he goes along with what he believes is a charade. Meanwhile, the Master of Absolute Evil, Heug-un, has freed himself from the prison he was sealed in by the Seven Masters. Only Maruchi can prevent Heug-un from plunging the world into dark chaos.
