Chu Hui, more commonly known as the True Master, is an ally and mentor of Robin.

Character HistoryEdit

When Robin first encountered and lost a fight to the villainous martial artist Katarou, the latter implied that he had been trained by the legendary True Master. From what little information Robin could gather, the True Master lived on a mountain somewhere in Asia, and only the most serious of students would ever have a chance to be trained by him. Intent on improving his fighting skills and to eradicate the blot on his honor, Robin departed for the True Master's abode.

In the village at the foot of the mountain, Robin encountered an old woman named Chu Hui, who followed him up the mountain giving clues Robin did not (or did not want to) understand and scolding him for his impatience. After many hazardous tests, Robin arrived at the top of the mountain, only to be intercepted by Katarou. In fact, Katarou had not trained with the True Master yet, but intended to do so now. He had goaded Robin into seeking out the Master, let him bypass the tests in his stead and thereby pave the way for him. Now Katarou sought to collect his unrightful prize.

At the verge of loss, Robin was encouraged by Chu Hui to rise and meet Katarou in battle, despite his fatigue, and take what was rightfully his. Using the experiences Robin had gained from his journey, he defeated Katarou. And it turned out that Chu Hui was in fact the True Master; she denounced Katarou a cheat and had her trial guardians throw him off the mountain. After wryly chiding Robin for taking her challenge too seriously, she accepted him as her student.

Powers and abilitiesEdit

While being well past her age-related prime, Chu Hui is physically and mentally still very capable, and a legendary master of the martial arts.
