Shenhua has medium length black hair and brown eyes (brown and hazelnut in the anime). She has some of her hair tied in two chignons that she has covered. Shenhua is mentioned to look exactly like her twin brother Shenyun, with her chignon the only way to tell them apart.
Shenhua is arrogant, shrewd, and sadistic. Like her brother, Shenyun, she treats her opponents as toys rather than people. In battle, she prefers to set up situations favorable for herself and Shenyun, making themselves untouchable while hounding on their opponents' weaknesses. They never beat their opponents easily even though they are able to do so, preferring to see their opponents struggle and despair. They are deemed to be despicable enough for Hufeng to expressed his disgust of them, noting that "no one could ever get along with them". Typical of a member of the Water Faction, Shenhua looks down on members of the Wood Faction.
Shenhua tends to fall in love with people easily and according to Shenyun she doesn't have a good eye for men, forcing him to protect her from unworthy potential boyfriends. She is also implied to be somewhat of a brocon, as she was inwardly annoyed when she realized that he had another potential girlfriend.
Unlike Shenyun, she prefers sweet food in addition to different music and movies.
In the past, when they were small children, both Shenyun and Shenhua were sold by their parents to Jie Long. Soon after, their skills were recognized by their instructors and both were given training in seisenjutsu.
