My sister, Lin Xiaoyu, asked me to braid and blow-dry her hair during the day, and at night she swept across the street with a baseball bat. Until I discovered that there were two souls living in her body: one was a frightened cute sister, and the other was a cold-blooded empress who traveled from a parallel world. Now, all the underground forces in the city want to kill her, the mastermind behind the scenes wants to capture her, and the two souls are still fighting for her body. And I am just a convenience store cashier, and my only skill is: no matter who she is, she is my sister.
