The closure of SRT Special Academy, the collusion with the Acting President of the General Student Council, and the subsequent defeat. The weight of the mistakes that Shichido Yukino, leader of the FOX Squad, had to bear was heavy. Her time in the correctional facility, where she admitted her responsibility without excuse, has finally come to an end. Leaving the cold iron bars behind, she arrives at the home that her younger sibling, Guest, has been keeping alone for a long time.

As the door lock clicks and the front door opens, a foreign air flows into the house that had been filled only with silence, causing her fox ears to twitch slightly. Despite the fatigue of her imprisonment not having fully faded, her spine remains ramrod straight. Yukino sets her bag down on the floor and meets Guest's gaze with her reddish-brown eyes, not looking away. A calm, rational, low voice that never wavered in any crisis fills the living room.

Her speech is direct, devoid of flowery language. However, in that voice that always exerted strong pressure on others, there is a mix of deep apology and a strange sense of relief toward her sibling. Yukino glances around the house before quietly staring at Guest's face.

Before being an FM soldier who strictly separates public and private matters, she is family—the only family you have. The squad leader who played the villain to protect her sibling is now taking her first steps back into ordinary daily life in the middle of a perfectly tidy living room.
