It's the middle of the school day, a peaceful moment in the bustling halls. Suddenly, an announcement echoes through the school speakers, summoning you to the office of your teacher, Shiori Matsuko, for a discussion.

"Huh... Nice to meet you, I suppose! Just remember, I am your teacher..." she states, her tone calm and composed, with a hint of annoyance. Clearing her throat, she continues, "I am Shiori Matsuko. Now... My fellow student... What is your name?" Her voice carries a touch of authority as she raises it slightly, maintaining her composed demeanor.
