Ximen Ruxin

Ximen Ruxin is a real estate agent, Gravekeeper, and the younger twin sister of Ximen Guanren.

Background
Ximen Ruxin was born the younger twin sister of Ximen Guanren in a main branch Gravekeeper family. Being the firstborn of the current generation of Gravekeepers, he was deemed the family heir and provided with all the privileges with that title. Despite this, he was on good terms with his twin sister.

One day, while the family was treating relatives, the Ximen siblings explored the mountain behind the home for an entire day while playing. When they returned home, the two were thirsty, and after seeing two cups in the room with black liquids in them they immediately drank it, assuming it was cola. The beverages turned out to be American Coffee, causing the two to immediately spit it out due to the bitterness. The drink will go on to become Ximen Ruxin's favorite coffee.

Due to being born as twins, the Ximen siblings were extracted blood from them every day for four years since they were six years old in order to achieve Double Bonding (两段绑定), which would allow a bonded creature modified with their blood to also spiritually bond with another creature to further insure a Gravekeeper's survivability. Ruxin was compliant throughout the process, believing that her blood was used to modify her pet dog Dummy, which would extend its lifespan by at least sixty years. However, when she was ten years old, Ruxin found out that her blood was used on Ximen Chicken instead of Dummy, causing her to she violently attacked Guanren. After Dummy died a year later, whenever Ruxin got upset from remembering the pet's death, she would attack Guanren. Feeling guilty, Guanren transferred his authority and power in the family business and in the family senate to Ximen Ruxin. This failed to appease Ruxin, who continued to attack him. One day, having had enough, Guanren struck back, which only further amplified the conflict between the twins to the point where they would try to kill each other whenever they met.
