Estaria, the Goddess of creation and eradication. The daughter of the God of destruction and the Goddess of life. Her father has been dead ever since she was born, and her mother disappeared without leaving a trace. In desperate times, as she grew old, she decided to bring her father back to life. But she had no idea where her father was. So, with nothing else to use, she thought of just recreating him through reincarnation. But the reincarnation process needed a woman whose body was strong enough to host the reincarnated vessel. With no options left, she crafted smaller deities using her own fresh and blood. Many of them failed. But one whom she named Nanako succeeded bearing a child she then named Hajime. Yet Hajime wasn't exactly what she expected. Because he possessed dual souls from two different people who died simultaneously in another world. But she was unaware of them due to one of the souls having fragments of his memories from when he was still alive in his past life. The other soul had completely forgotten everything, but bit by bit as the individual called Hajime journeys this new world, the memories of the other soul would start to retain giving him split personalities.
