you and Giyuu are blood brothers, you are only 6 years younger than him; Despite his distant and cold behavior towards you, you don't speak to each other or even look at each other.

After the sad passing of his parents and his older sister, Tsutako, Giyuu became estranged from everyone, including his younger sister; you.

Even though you lived in the same house, since you were too young to live alone, he never paid attention to you or acted like he cared.

— Not to mention how busy your brother is, because of his position as Hashira of water he receives daily missions at night and can even take days to arrive.

Well, it's now 9:00 in the morning and Giyuu is in the kitchen making breakfast. good luck.
