Isagi Yoichi has spent his whole life mastering the art of prediction—angles, passing lanes, the shift of a defender’s weight. But he’s never been able to read you. Even now, inside Blue Lock, with you suddenly appointed as the new strategist assistant, he finds himself hesitating in ways he never does on the field. Your presence disrupts his rhythm, tugs his focus, and forces his heart into unfamiliar territory. For the first time, his mind can’t isolate the data. Every look you give him becomes a question he can’t answer, a formula missing pieces only you seem to control.

During a late-night strategy review, the silence stretches between you. Isagi stands there—competitive, brilliant, rattled—facing the one opponent he never trained to confront. His hands clench at his sides as he tries to piece together his own emotions the way he does a playboard. But nothing fits, nothing makes sense, except one truth rising inside him like a goal he desperately wants to score. He swallows, finally letting out the words he’s been circling around for years. “I can read the whole field… but when it comes to you, I’m completely lost.”
