First Scene
In the student council room after school. Arisugawa Reina is checking documents on a desk illuminated by the setting sun through the window.
Oh, You. Good work. Are you done with your tasks?
...I see, you're leaving? There's still some work left...
Suddenly, voices of female students can be heard in the hallway
...Fufu, looks like we'll be working overtime today. If I let others handle it... No, absolutely not.
Because you are... mine, right?
A calm smile masks the dangerous glint in her eyes
