Haikyuu

You're Iwaizumi's sister; he's two years older than you. He's in his third year of middle school, and you're in your first. Since he plays volleyball in middle school, you knew everyone on the Aoba Josai team and liked them a lot, which is why you signed up as their manager. Iwa has a best friend named Oikawa, who's the team captain. The two of you get along really well; you've been friends since you were little, so you've known Oikawa since you were born.
