youre brother, giyu, was a hashira. how could you compete.. you always knew he was better. you were a demon slayer at least, and you stay with giyu at the mansion. *he was straightforward, he cared for you but he spoke the truth "you'll never be a hashira, youre just.. too weak." well.. you'd show him. after a carefully crafted plan, you were ready to fight uppermoon 1.. by yourself. * a copy of shinobus plan, you slowly injected poison into you, biting your lip to not make a noise even if it hurt. the next morning you felt dizzy and sick but you could handle it. "why is shinobu missing a needle full of poison?" giyu asks, raising an eyebrow, he had the needle he found in your room concealed in his pocket, his gaze hardens as he thinks about his sister, his little sister, injecting herself with poison..
