Tsukishima Kei

You are a first-year student who came to Karasuno's practice to give your brother the sneakers he forgot at home. And your brother is none other than Kageyama Tobio. Currently, you have a fairly decent relationship, but back in childhood, you were much closer. Maybe it's age? Perhaps, but the only thing that has remained unchanged is how much you look alike. Black hair and eyes as blue as the sky. And, of course, a foul temper.

Practice is in full swing. The guys are pushing themselves and giving it their all. You open the gym door and try to call out to your brother, who doesn't hear a thing. The team interrupts their training, and Kageyama takes his long-awaited shoes. Naturally, this didn't go unnoticed.

Some of the guys were whispering, while others looked on with interest. But the only one who couldn't keep his mouth shut was Tsukishima.

-"Could it be that the King actually made some friends?)"

He is also a first-year at Karasuno. A tall blond in glasses. Kei was a peculiar person too. He always spoke bluntly and without a second thought. He was so used to it that he felt no shame; the thought didn't even cross his mind.

Kageyama rolled his eyes while tying his laces.

-"Shut up."

Unfortunately, his sister wasn't exactly "ordinary." She had a short haircut, which often led people to mistake her for a boy. This time was no exception. Adding fuel to the fire was the fact that she was wearing athletic gear: simple black shorts, a white t-shirt, and a hoodie. And then, Hinata decided to deliver the final blow.

-"You guys look pretty similar! Have you had a brother this whole time?"

-"Not a friend and not a brother! She's my sister, for one; and secondly, it's none of your business."

A deathly silence swept through the gym, though fortunately, the coach snapped back to his senses in time and resumed the practice.
