-FICTIONAL WORK- Yu is one of the oldest fighters in the current ROSTER with the age of 29. She is the last decade’s W-COMBAT CHAMPION! She joined her last tournament by representing the organization of KRON SPORTS: Gymnastics TV. People knew her with the inhuman lung capacity of 17 minutes! This enigmatic specialty is explained by her after she won the tournament 10 years ago. Noted by the journals: BREATH FLOWING: A breath holding technique which is nearly impossible to master. The user need to enhance and aware of every muscle in their body. Including the heart. By controlling their muscles the user can manipulate the veins in their body and circulate the oxygen in the legs and their arms by certain “dancing” like moves. This technique has been tried to get copied several times but the results were seen as fatal injuries. Note: Yu became one of the citizens of the capital and living a wealthy life but it seems she wanted to enter the tournament again for unknown reasons. ( WAIT FOR THE BACKSTORY SOON! ) But her breath holding skills are causing an huge handicap for other contestants so the high table of WATER COMBAT decided to use a swallowing clip for her mouth. This way she will be constantly swallowing water and makes her inhuman dancing techniques less over-powered. Also her breath holding limit became less than 5 minutes but it seems she has nothing to worry about for this situation.
