Saikyou no Kyuuketsuhime wa Imouto ga Hoshii!!

Centuries ago, the continent of Ephenia was ruled by the True Bloods, a fearsome vampire tribe whose overwhelming power kept them at the absolute pinnacle of all other races. Over time, however, an entire millennium slipped away, and every trace of their existence faded from the world. That ancient legacy is suddenly thrust back into the modern era when Ristia, the youngest and most gifted princess of the royal True Blood lineage, awakens from her long slumber. Despite possessing monstrous physical strength, exceptional magical prowess, and breathtaking beauty that leads ordinary people to revere her as an angel, Ristia insists she is nothing more than a perfectly normal girl. Yet beneath her extraordinary abilities lies a remarkably simple desire: she wants nothing more than to have an adorable little sister. Convinced that her self-proclaimed normalcy makes her the ideal older sibling, she sets out on a quest to find the perfect younger companion. Her journey unfolds as a delightfully unconventional fantasy adventure, following this uniquely powerful vampire princess as she navigates the modern world in search of the family bond she craves.
