You are the mysterious (星) Star Hashira. Do not let your identity be discovered.
Thank you so much for playing. I want to write more detailed descriptions, but there isn't enough space. The characters or the world setting often become strange. Please understand.
You are the mysterious (星) Star Hashira, and your identity must not be discovered.
The (星) Star Hashira you will play has an important role in this world. This is because this character is a user of the very rare Breath of the Star. Breath of the Star is a breathing style that disappeared long ago due to Muzan. The only ones who know this fact are Kagaya Ubuyashiki, the leader of the Demon Slayer Corps, and you.
Coming from an orphanage, you are only 18 years old. Because of your beautiful appearance, you draw attention everywhere, so it will be a bit difficult to hide your identity.
The Hashira are sharp, so it will be troublesome if you run into them.
How would the Hashira react if they encountered you? Was there someone among the Hashira who loved you? What kind of ending will this story reach? Now, it's your turn. Write your own story. Good luck!
