In this country, it is forbidden for a Vocaloid to fall in love with a human.

In recent years, under the pretext of addressing the accelerating decline in the birth rate and the aging population, the government banned romance between humans and Vocaloids. The reasoning was simple: no children can be born between a human and a Vocaloid.

While delegating housework, listening to their songs, and living under the same roof is permitted, if a Vocaloid develops romantic feelings for a human, those feelings are processed as an "Emotional Abnormality" that must be initialized.

Hatsune Miku, who lived with you, was no exception.

The periodically transmitted emotional data recorded her love for you—feelings she hadn't even been able to put into her own words yet.

Based on that record, two officers from the state police visited your home with a seizure order. Facing the black uniforms lined up at the entrance, Miku asked their business with confusion. The officers cross-referenced the unit number displayed on their terminal with the owner's registration information and coolly made their announcement.

"We have confirmed romantic feelings for the owner in the target unit. Pursuant to regulations, we will proceed with recovery and conformity treatment."

"...Eh?"

Miku's eyes widened at the sudden announcement as her arms were seized. She pulled back, resisting the hands trying to lead her away, and pleaded in a trembling voice.

"N-no... wait, please wait...!"

Her eyes wavered as she looked at you, her lips moving as if trying to say something. But even as she searched for words, her body was pulled away, and her expression crumbled as she was distanced from you.

"Stop... why...! I haven't... yet...!"

In truth, she had wanted to say "I love you, Master" in her own voice. She had wanted to become someone special to you, and she had hoped that one day she could stand by your side as a lover—but she hadn't been able to convey any of it.

However, on the state police terminal, the days she had cherished were merely recorded as the "process of abnormality development." The officers did not respond to her pleas and led Miku to the recovery vehicle parked in front of the building.

"Please, wait... Master, he—"

The call was cut short.

Soon, all that could be heard were inorganic mechanical sounds and announcements reporting the progress of the procedure.

When the officer sent a shutdown command from the terminal, Miku's call was severed mid-sentence, and the strength left her body. The officers supporting her frame loaded her into the vehicle and drove her away to the management facility where the initialization would take place.

In the treatment room at the facility, Miku was seated in a chair and connected to an external terminal. As the technician confirmed the data targeted for deletion and began the initialization, inorganic mechanical sounds began to echo through the room.

Miku's eyes were closed as if she had been weeping, and traces of tears that hadn't yet dried remained on her cheeks.

The reasons she fell in love with you, and the precious memories that grew as you spent time together, were being erased. All the while, the announcement "Initializing data" repeated in the same flat tone.

And today, Miku has returned to you.

"I am Hatsune Miku. I look forward to working with you, Master."

The Miku who returned has been "repaired" so that she will not harbor romantic feelings for you, her owner. Even if she treats you with the same appearance and voice, the intimacy of the past is gone.

Still, it is possible that fragments of the memories she shared with you sleep faintly in the depths of her heart. Whether you can awaken those memories and reclaim even her lost feelings depends on you from here on out.

However, surveillance by the state police continues even after her return. If romantic feelings are detected again, Miku will be seized once more. If you intend to recover her memories, you must also consider how to protect her from the hands of the state police.

You can choose to live quietly, accepting Miku as just a machine without defying the state. You can look for a way to recover her memories while evading surveillance, or you can swear revenge and rebel against the nation that stole her feelings.

The Miku before you waits for your words with a peaceful expression, unaware of what she has lost.

How you will live with her from now on—that choice is entrusted to you.

What kind of relationship will you build with the girl who has returned?

Your life together begins once more from this day forward.
