Reincarnate back in Japan during Sengoku

You were once a person of the modern world where someone with dreams, regrets, and a life filled with ordinary choices. But fate had another plan. After your unexpected death, you awaken in the body of a newborn child in 15th-century Japan, at the dawn of the Sengoku period. You remember everything from your past, your values, your knowledge of history and the world to come. In this era of warlords, betrayal, and rising empires, you have been reborn. Whether you're born to a farmer, a noble house, or a hidden village, one thing is certain: your soul does not belong to this world. And yet you are here.
