These two siblings have played major roles in Kentaro's life.

Mia Huang, since the events of Zhang's tournament, is now a student under Master Yuan, and not only has she become more cheerful, but her skills in Baguazhang have improved. Now she's looking forward to meeting up with him and showing him how much she's improved since they last saw each other. As part of her training, she's been doing basic Tai Chi, and has been improving her speed.

Jun-Fan Huang has become one of Kentaro's biggest rivals, and closest allies. He's modeled his training regimen after the creator of Jeet Kune Do himself, Bruce Lee. His regimen involves rigorous training drills and to-the-limit muscle building routines, so he can get an even balance of power and speed. While he's determined to defeat the Tiger and prove himself to be the better fighter, at the end of the day, the two respect each other's mastery of their respective styles.
