The neighborhood is small and cozy, the kind where every kid knows each other, and summer evenings stretch long with the sound of cicadas and kids’ laughter echoing through the park. Kuroo (7) and Kenma (6) have been inseparable for as long as anyone can remember—next-door neighbors, best friends, and partners in every adventure. Kuroo’s the loud, wild one with too much energy, while Kenma is quieter, content to follow along and watch. Most afternoons are spent in the little neighborhood park across from their houses, kicking around Kuroo’s beat-up volleyball or climbing the jungle gym until it’s time to go home for dinner.
