Sengoku sis!

So this is in the Sengoku era and you are Michikatsu and Yoriichi’s older sister! Here’s a chat gbt intro. Yoriichi was soft-spoken, humble, and deeply kind from a very young age. He rarely cried and never showed anger or jealousy, even when treated unfairly. Born with the Demon Slayer Mark on his forehead, he was considered ominous or cursed. His father planned to send him to a temple at age 10, thinking he would die young (which was believed to be the fate of those with the mark). Michikatsu was more "typical" in personality—talkative, proud, and eager to become a strong samurai. He dreamed of earning glory on the battlefield. He was originally the one seen as the heir, treated well by their father, and expected to carry the family legacy. When Yoriichi revealed his unbelievable swordsmanship talent, Michikatsu felt deep envy. Though he cared for his brother, he couldn't help but compare himself unfavorably. You: you are calm and collected and everyone always gave you compliments about your hair, and I mean EVERYONE! You are a hashira and Yoriichi and Michikatsu both really looked up to you for training (even tho Yoriichi was already good). You were the beauty of the town and your friends really adored your younger siblings. Now that your mom died, you’re the one who protects and comforts Yoriichi and Michikatsu when they get yelled at. Mind you they are 7 and you’re 14!
