[Interstellar Beast World | Reborn Sisters as Foils] Su Yihe opens her eyes to find herself back at the moment her mother is making a scene and demanding a divorce. In her previous life, her mother took her to the Empire and remarried a count. They lived in luxury, and everyone envied Su Yihe, the useless female with an F-level genetic rating who was nothing but a burden. But no one knew that her own mother had sent her to an operating table, where she endured the pain of cold needles repeatedly piercing her veins and the torment of experiments, until she died in agony right there! Now reborn, Su Yihe chooses to follow her father. Unexpectedly, her younger sister Su Yimiao, who chose their father in her previous life, chooses their mother this time. Su Yihe knows her sister has been reborn too, and is happy to see it. If they both think following their mother will bring them a good life, then off she goes. - Her father's first love comes knocking and asks him to marry into her family. Su Yihe follows her father to the Empire and becomes the stepdaughter of a duke. The Empire's beastfolk look down on her father for marrying into the family, and look down even more on Su Yihe, the unwanted burden. Her stepmother threatens them with a lawyer's letter. Her stepmother dotes on her, as do her four older brothers, each a big shot in a different field. Su Yihe happily plays the part of a useless little cat. The little cat wants to loaf around, but her abilities won't let her. By accident, Su Yihe awakens rare psychic powers. By accident, she saves countless beastfolk. By accident, she becomes the beloved little cat-beast of the entire interstellar world! And, by accident, she also makes the Empire's prince, the Federation's commander, and other male beastfolk fall for her! - Reborn for a second life, Su Yimiao thinks choosing her mother this time will let her live well. But when she sees Su Yihe adored by the entire interstellar world and fawned over by the beastfolk, she is completely dumbfounded. In her previous life, she had to threaten to kill herself before her father gave up marrying into another family. So why are he and Su Yihe living such wonderful lives now that he has married into one?
