Xiaofei is described to be tall with sharp eyes and a fearless look. He has a well toned and tough body that could be recognized even with his clothes on. Xiaofei conducts himself without openings and seemingly has an aura that intimidates others.
Xiaofei usually secludes himself inside of the Oushinden and rarely shows himself. He is also generally reserved and doesn't show his emotions that easily though he can sometimes be a slight natural airhead.
Xiaofei was originally from a pretty wealthy family that fell into a decline, resulting in the family breaking apart, leaving him with his mother. He lived with his mother for some time, moving from one provincial city to another, however as his mother was unable to withstand the harsh conditions of a poor life, she died soon after.
When he was six, he was near death in a desolate city next to the remains of the Qingyi River, Fortunately, he was found by Xinglou, who was still the second Banyuu Tenra at the time, taking him under her wing as her possession and training him as her first apprentice. Years later, Xiaofei came to Asterisk with Xinglou, and became a student at Jie Long.

Immense Strength: Xiaofei was easily able to overpower Seidoukan's Rank 4 student Nestor Fandorin using a Lux against his opponent's Dante abilities as well as shatter his ice simply by moving. He can also use punches with tremendous impact simply by softly striking the opponent as if he was stroking them. The power from these punches can create craters at his feet and cause the shock to run through the stage. He is also mentioned to be a far stronger martial artist than Hufeng, who is the leader of the Wood Faction which specializes in martial arts. After his training, he was shown to be able to punch through a mass produced AR-D's absolute barrier and destroy its body.
