Liu Yunfei (Chinese: 劉 雲飛; Pinyin: Liú Yúnfēi; Japanese: 劉 雲飛 Ryū Yunfei), also known just as Yunfei, is a character introduced in Samurai Shodown V.
In their commentary for fans, developers reveal that his character was a request from the director. He wanted to make another overseas Asian character to give more contrast to the newer cast. At first, they were designing for a lady until several designers began to fear making her similar to Chun-li. Since they were already making a "new young lady" (Mina), Yunfei was eventually modeled to be the "cool old guy".
He lived at one point in 800 A.D. with his wife. Desiring to gain more power, he made a deal with a demon being calling himself "The Dark Emperor" (Kuraki-sumeragi) which caused him to go berserk. He killed his wife before he is sealed into a boulder by his eight students (according to SSVI, two of them were Enja and Suija).
A millennium later, he is freed due to the entity leaving him to possess someone else. Wanting to redeem himself, he tracks down the entity's source with intents to exorcise it. In his ending, the entity is found in Gaoh and it begins to overwhelm its host. In order to help Gaoh, Yunfei takes possession of the monster's body and urges the free Gaoh to slay the demon. He is struck down and is reunited with his wife (presumably in heaven).
Haunted by his past, Yunfei became a bitter, yet honorable man, seeking to the destroy the Dark Emperor for redemption.

Yunfei's fighting style is based on Chinese broadsword techniques. He takes most of his mannerisms from typical wuxia traits. The most notable of these is his ability to float through the air, an exaggerated approximation of qinggong or lightness skills.
