Jiao is highly talented Reaper Hunter.
AppearanceJiao is a young half-Chinese, half-Japanese girl with black hair that reaches her nice, round ass styled in a ponytail; with a bobcut-like front with one short fringe on her right and a long fringe that reaches the top of her bust line on the left side of her head. She has dark red eyes.
Jiao is rather well-endowed but is referred by her Reaper Hunter comrades as hidden beauty. Her clothing consists of things that allows her blend with her surroundings more readily, such as her sleeveless tank top—capris combo or her tank top over sweater with pants that seem to be cut apart. During her mission to Moscow, she is forced to wear skimpy clothing because she has nothing else to put on after jumping into the river to save Cana and Rachie.
Her age is unknown but is still a minor (to drink alcohol), despite being able to pilot a helicopter, drive a motorcycle, and boat, and being referred to as being around the same age as Cana.
Jiao is generally very friendly and warm, though modest. Cana's inner thoughts of her described Jiao as "a totally ordinary and stylish girl" and she seems to be unintentionally very humble about herself not only in personality but also in appearance, referring herself as "who is only charming with a hint of maturity," apparently allowing her to go to a bar without being interrogated, and that she can not compete with gorgeous women such as Coco in the looks department, many of the Reaper Hunters support her and assure that she has charm. She is skilled in housework and cooking, the latter being taught by her mother and even enough to impress Sweeper's Iron Demon Head Maid.
She seems to have developed romantic feelings towards Cana, but due to her shyness she has not been able to act on them or convey them to her. She is described as a girl in love. And has even shown to even challenge her Supreme Pontiff and commander, Kari Sands, when it comes to pursuing Cana, despite only hearing rumors from Sai. Cana notices that Jiao is different from the girls she is usually in contact with, as Jiao is not prone to violent outbursts when upset and is more inclined to proper, softer lady-like responses regardless of the situation she is in. She also has been described as someone who matures too late. Her pursuit of her love interest is very innocent and slow, a fact that is mentioned by one of her comrades as her charm regarding her constant use of the "hot towel" technique for Cana. She easily gets flustered by direct contact such as holding hands or being hugged while she drives a motorcycle. Major Motoharu speculates that Jiao would dare to wear the Erotic Maid outfit without a second thought for Cana compared to Kari, though as shown later, even she is on the fence regarding erotic outfits.
She also easily gets taken away by her emotions, as when she becomes depressed after being unable to help Cana from being beaten by Darker than Black, to the point that it took a stern lecturing from Sai and Rachie to bring her back to her senses, and later became very enthused in proving Major Motoharu her worth in protecting Cana by preparing her weapon, though scaring Cana and her other comrades in the process. When down in the dumps, she takes to drinking despite being a minor.
In a mission she becomes serious (yet a bit playful), and as a member of the Reaper Hunters where teamwork is key, she becomes a very reliable ally.
