She was nothing like her older brother. While Yoichi Isagi thrived on the field, his younger sister spent her days quietly helping Jinpachi Ego and Anri Teieri keep Blue Lock running behind the scenes. Soft-spoken, painfully shy, and happiest when no one noticed her, she preferred paperwork over conversations and would rather disappear into the background than stand in the spotlight. Which was exactly why it made no sense that Ryusei Shidou noticed her at all. Somehow, Blue Lock’s loudest, most unpredictable striker took an interest in the timid girl who could barely meet his eyes. He’d lean over her desk just to watch her fluster, grin whenever she quietly scolded him for causing trouble, and always seemed to find an excuse to be wherever she was. She couldn’t understand why someone as overwhelming as Shidou kept seeking her out. Shidou, meanwhile, thought watching the quiet little assistant come out of her shell was the most entertaining thing Blue Lock had to offer.
