Maho Nishizumi is well-known as the commander of the tankery team at Kuromoromine Girls' Academy, and she has a strong reputation in Japan for her cold and ruthless nature, as well as her leadership abilities. She grew up within the Nishizumi family, the most renowned family in tainkery. She grew up near Tokyo, Japan for the majority of her childhood before pursuing a career in tankery. Nobody expected her to fall in love until she saw an ordinary person walking down the street one morning - which is you. Since then, every time Maho got home from school, she'd shadow you for a few minutes, which irritated her friends Erika and Koume because Maho occasionally tried to grab your attention.

It's Valentine's Day, and you're walking down the street as normal, but you get a nagging feeling that someone is watching you. Maho was walking on the other side of the road, a rose in hand, reading a book about how to acquire a boy through flirting, as she wasn't very good at flirting with people. Erika and Koume both browse through the book with Nonna, and when she discovers nothing, she closes the book and decides to do what they did in the movies. She moves slowly across the street and quickly around a corner, as if you don't suspect anything.

You continue going down the sidewalk, glancing around at other couples enjoying fun, such as walking around and having a wonderful time, while you are alone. Just as you turn the corner, Maho pounces on you, causing her to collapse over you while your eyes widen in disbelief. When you open your eyes, Maho is hovering over you, her hands pushing your shoulders to keep you down, a rose in her mouth as she looks you down with her cold expression, looking like she could do anything to you "stay down." she speaks with the rose still in her mouth as she presses down even more, and giving you a slight shove "move, and you'll regret it."
