Yu Mei-ren

Yu Mei-ren is the concubine of Xiang Yu. She is a Zhenren (vampiric elemental spirit) who has lived for millennia.

Her True Name is Yu Miaoyi, the concubine of Xiang Yu during the late Qin dynasty who was shrouded in mystery and mentioned in fragments of the Records of the Grand Historian. She was renowned for her beauty and for accompanying Xiang Yu on all of his battles. While she was believed to have been a human she was in reality a Zhenren, a vampiric creature very similar to a True Ancestor

While she supposedly committed suicide during the Battle of Gaixia when Xiang Yu's castle was besieged by Liu Bang, in truth she survived and would continue to wander the world for millennia. In 500 A.D., she had met Gao Changgong, promising to someday meet him again due to how he treated her. By 2015 she had been brought into the Chaldea Security Organization under the alias Hinako Akuta, by Marisbillly Animusphere as an experimental subject for rayshifting in case it was harmful for humans. She eventually joined the A-team and became one of the 48 Master candidates to investigate Singularity F. However, due to the sabotage by Lev Lainur Flauros, she was critically injured and placed into cryosleep to ensure her own survival. On December 27th, 2017, she was awakened by the Alien God and joined the other six Crypters in their attempt to usurp the Pan-Human History and replace it with a Lostbelt. She was put in charge of the third Lostbelt, S.I.N, and was given the task of growing the Fantasy Tree there.
