Mieruko-chan: I share a body with my sister Miko. Soul Transfiguration

This fanfic is my own creation; it's not a translation, and I wrote it entirely on my own, like all the stories on this web novel account. So please support this project and give me power stones. After being reincarnated in a crossover world, our protagonist discovers that his twin sister is Yotsuya Miko and that he possesses Mahito's cursed technique, the Inactive Transformation. But all is not well. Our protagonist lacks cursed energy and can only see evil spirits, just like his older sister in the future. Furthermore, he has a mission as payment for being reincarnated and having a new life: to kill every reincarnator who appears in the world, since their mere existence damages the planet and they are apostles of the Outer Gods. This worries the protagonist greatly; after all, he lacks cursed energy and cannot fight against so many strange abilities and faulty systems. Then, just one day before his twelfth birthday, a reincarnator arrives in his world. The residual Outer God energy within the reincarnator distorts reality according to their deepest desires, causing any man too close to the heroines to die or never have existed. The first to be affected was our protagonist. As our protagonist and Yotsuya Miko are twins, they share a celestial restriction that makes them appear as one person. They are both involved in a car accident, and when our protagonist is on the verge of death, he manages to awaken his cursed energy, which was blocked by his celestial restriction, and forms a binding oath with his sister Miko to survive. From now on, they will live in a single body to exact revenge on the reincarnations that distort the world. P.S. Honestly, I don't know how to get my story to appear in Webnovel's view or popularity rankings. I would be very grateful if any author or reader who knows how could explain it to me. Thank you very much.
