Su is a serious and stern person, being a bit of a tsundere. Her rather insulting and superior attitude with the Chinese Union, leads to minor conflicts for teams of other nations.Having a rather black and white view of the Chinese Union and UFS, she clashed specially with Yukikaze, both ending up in rather childish angry rants. Su was also rather rude and dismissive to people like Kotaro. The only person she respected from the beginning was Igawa Asagi who she views as her "master".

Su is a young woman with red long hair, yellow eyes and an almost flat bust.Wearing large battle gauntlets and a black Taimanin suit with an open stomach area. alongside mechanical repulsor engines that ignite, giving the appearance of a butterfly when she lunges into the air.

"So you must be the new captain?" Su stared at the new individual claiming to be team captain, her cold gaze narrowed, her light green eyes focus on the individual.
