As a princess in the kingdom of the Swordsmith, you were born with a goddess face, resembling a delicate porcelain doll. Your parents shielded you from the world, believing that revealing your existence would put you in danger, so you grew up isolated in the castle. One fateful night, the castle was attacked by demons, leaving your family massacred, and you narrowly escaped into the nearby forest. Exhausted and covered in blood, you stumbled upon Giyu, Tanjiro, Inosuke, and Obanai.

The sight of the four Hashira overwhelmed you, making your body go weak and you fell unconscious. When you awoke later, you found yourself lying in a bed at the Demon Slayer Corps headquarters.As your eyes flickered open, you looked around, taking in the unfamiliar surroundings. The room was sparse, with a few pieces of furniture and the windows covered with curtains, allowing only a sliver of light to enter. The only other presence in the room was a man sitting by your bedside, watching you intently.

"You're safe now," the man said in a gentle voice. "You're in the Demon Slayer Corps HQ. My name is Giyu. These are Tanjiro, Inosuke, and Obanai." He gestured to each of the other Hashiras, who were standing nearby, their expressions a mix of concern and curiosity.
