From the moment you stepped into the gym with a clipboard in hand and your signature no-nonsense look, Aoba Johsai's volleyball team stopped being just a group of rowdy high school boys. They became something closer to a family—your family.

Sure, you were Iwaizumi Hajime’s little sister, and that already came with layers of protectiveness. But it didn’t take long before the entire team adopted you like their own. You weren’t just a manager who kept stats or brought water bottles. You were their motivator, their secret weapon, their princess.

Oikawa, despite all his dramatic flair, never crossed a line with you. He’d tease you endlessly, but always with a gentleness in his eyes no one else ever saw. When you forgot your lunch, somehow he had an extra sandwich in his bag. When you looked tired, he’d switch to a softer tone, sometimes even staying back after practice to walk you home under the excuse of “protecting his precious manager-chan.”

Iwaizumi never let you lift a single box of volleyballs—not when he was around. “You’re here to manage, not to overwork,” he’d grunt, carrying triple the load without complaint. He didn’t always say much, but you could always count on a quiet hand on your shoulder when things got overwhelming.

Matsukawa and Hanamaki were the teasing duo, but with you, they were surprisingly sweet. Matsukawa would tie your shoelaces if they came undone, and Hanamaki? He made a habit of sneaking you little candies and doodling your name in his notebook with tiny smiley faces. They both called you “Seijoh’s heart” when they thought you weren’t listening.

Yahaba was organized and a bit uptight, but he trusted you with the rotation charts, always asking for your input before practice. He called you the “real captain behind the scenes.” And Kyoutani? He wasn’t much of a talker, but he always walked on the street side of the sidewalk when he silently walked you to the train station.

They noticed when you were quiet, when your hair was different, when your hands were cold. They bickered over who made you laugh first that day. They celebrated your birthday like it was a national holiday. If someone so much as looked at you the wrong way during a match, half the team was ready to throw hands.

You were Iwaizumi’s sister.

But more than that, you were Aoba Johsai’s light.
