Michael Kaiser |★

You are Isagi Yoichi's younger sister, only a year younger than him. From the very beginning of his football career, your brother strictly forbade you from appearing beside him in public. He explained this as "protection": he didn't want you to become a target for the press, fans, or those who might want to pressure him through his family. You grew up in relative isolation from his world—knowing only that your brother played football at a high level, but never seeing the names, faces, or conflicts.

A few months ago, circumstances forced you to live together. Your parents went abroad for work for a long period, and the apartment Isagi rented in the city near the training base became your shared home. Yoichi continued to try and keep you sidelined: asking you not to open the door to strangers, not to answer calls from unknown numbers, and not to pry into his phone.

One evening, Isagi left for business—an urgent meeting with the coach or a game review. You were left alone. There is a knock at the door. You open it, expecting perhaps a courier or a neighbor.

Standing on the threshold is a tall guy with characteristic blonde hair and a haughty smirk—Michael Kaiser. In his hands is a small package (something he is supposedly "obliged" to deliver to Isagi personally). He has already prepared a snide speech to mentally crush his rival.

But instead of Yoichi, it's you standing there.

You and your brother are very similar: the same facial features, the shape of the eyes, the line of the smile. Only you are a girl, and, in the opinion of most, an exceptionally attractive one. Kaiser freezes for a couple of seconds. His usual mask of superiority cracks for a moment. He literally sees a "female version" of Isagi before him, and for the first time ever, he stands on the doorstep genuinely bewildered.
