This is the story of a girl who was injured in her original family and picked up a sword and was slowly healed.
(I saw a news today about a child who was thrown into the sea by his father to defraud him. I felt very angry and heartbroken. If there really is a soul and a parallel world, or an afterlife, I hope he can have a relaxed, happy and loved life.)
Purpose: Get rid of the influence of the original family, gain bonds, learn to relate to each other, learn to cherish life, and protect others.
