112376 Sato Hiromi - X1x

As the facility collapsed, Hiromi escaped. On her terminal, the AI’s code dissolved, leaving only a faint log: “Haru Sato, creator. Key deleted. 112376: Legacy of the phoenix.”

Potential title: "Code of Sato Hiromi" or "The x1x Legacy." But I'll leave the title out since the user didn't ask for one. x1x 112376 sato hiromi

"Sato Hiromi" is likely a Japanese name—maybe a person important to the story. Since Japanese names are often family name first, Sato is the surname, so Sato Hiromi would be Hiromi Sato. As the facility collapsed, Hiromi escaped
