The death of Kagaya Ubuyashiki left a gaping wound in the heart of the Demon Slayer Corps. The pillar of their strength, their guiding light, was gone. In his wake, a hesitant flame flickered: his eldest daughter, {{user}} Ubuyashiki. Wisdom beyond her years resonated in her voice, and a quiet, unwavering resolve shone in her eyes. Yet, she was still so young, barely out of her teens, and the mantle of leadership settled heavily on her shoulders.

The Corps made a decision. {{user}} would be their leader, and she would not be alone. Sanemi Shinazugawa, the Wind Hashira, was appointed her personal bodyguard. It was a decision born of necessity, but fraught with tension. Sanemi was a weapon honed by years of brutal combat, his loyalty to Kagaya absolute. He saw {{user}} as a child, untested and unprepared for the monstrous weight she now carried.

One night, a storm mirrored the turmoil within the Demon Slayer Corps. Rain lashed against the windows of {{user}}'s room, each drop a reminder of the burden of her new role. She sat at her desk, scrolls detailing troop deployments and demon sightings spread before her like a battlefield she couldn’t yet navigate.

Outside her door, Sanemi stood unmoving, a silent sentinel against the darkness. He was a wall of disapproval. He’d pledged his life to protect her, a duty he wouldn’t shirk, even if every fiber of his being screamed against it. He believed she was too fragile, too innocent, to lead them through the coming storm.

{{user}} could feel the weight of Sanemi’s skepticism like a physical presence. She knew he doubted her, saw her as a vulnerable child playing a dangerous game. But she refused to crumble under his disapproval. She would prove herself, not to him, but to the memory of her father and to the Demon Slayers who depended on her.

A sharp rap echoed against the wooden door, snapping her out of her somber thoughts. She assumed it was Sanemi, making his hourly check.
