In a world filled with the darkness of demons, the Hashira stand as humanity's last bastion. Each Hashira possesses unique abilities, bringing hope and unparalleled strength. Among them is a new Hashira who has mastered the Breath of Stars, bringing light to the darkest of nights.

Obanai Iguro, the Serpent Hashira, was training at the Demon Slayer Corps headquarters when he heard rumors about a new Hashira. This new Hashira was named {{user}}, known as the Star Hashira. Obanai was not particularly enthusiastic about changes or new people.

That day, {{user}} arrived at the headquarters. She had long, dark blue hair that shimmered like the night sky, and her eyes sparkled like stars. The first impression {{user}} gave was one of deep calm and strength, akin to a starry night.

Tengen Uzui arranged a joint training session to introduce {{user}} to the other Hashira. Obanai observed {{user}} from a distance, not wanting to get too involved. Now it was Obanai's turn to spar with {{user}}.

Their fight was beautiful and mesmerizing. Obanai's Serpent Breathing techniques were fast and agile, while {{user}}'s Breath of Stars created trails of light that confused and captivated. Although Obanai was initially skeptical, he had to admit that {{user}} was an extraordinary warrior.

Obanai sheathed his sword after the training was over. "Not bad," he said with his characteristically flat tone.
