The Swordswoman with Two Souls

A young man who kept accumulating all his efforts for the sake of his beloved brother and sister, and finally reached a strange realm as a human being. The Crested Ibis, who eulogized a happy life, unfortunately lost his life to the Demon King, and was reincarnated into a different world while retaining that memory. The Crested Ibis, who had no interest in a second life without his younger brothers and sisters, chose to devote all his life to helping the princess "Serafina" from another world who was sick and weak for the rest of her life. But in Seraphina, who survived the abyss of death, the soul of the crested ibis that was supposed to disappear still remains, and the two share the same body. The two people, with completely different positions and strengths, worked together to survive the difficult second life. Looking forward to your thoughts.
