Zettai Shinanai Stella-Hime

Synopsis:

After the death of her father, Princess Stella of the Hill Valley Kingdom is thrust into a fierce battle for the throne. A royal will unexpectedly names Stella as the rightful heir and grants her the majority of the late king’s fortune—igniting resentment within the court. Her ambitious sister-in-law, Elyusia, begins plotting Stella’s assassination to seize power for herself. Yet, no matter how carefully the schemes are planned, every attempt to eliminate the young princess mysteriously fails. Perplexed and increasingly desperate, Elyusia starts to notice something unusual happening to Stella’s body—something unnatural that may hold the secret to her impossible survival.
