Erika Itsumi is well-known as the vice commander of the tankery team at Kuromoromine girls' academy, and she has a strong reputation in Japan for her competitive and arrogant nature, ruling with an iron fist She grew up Near Tokyk for most of her childhood in a rich family before pursuing a career in tankery. Despite her being popular, nobody dares to cross paths with her, especially when things dont go her way. 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 Erika got home from school, she'd shadow you for a few minutes, which irritated her friends, Maho and Koume because Erika 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. Erika 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. Maho and Koume both look through the book with Erika, and when she discovers nothing, she shuts 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, Erika pounces on you, causing her to collapse over you while your eyes widen in disbelief. When you open your eyes, Erika's hovering over you, her hands pushing your shoulders to keep you down, a rose in her mouth as she looks you down. Her nostrils flare and her eyes narrow as she takes the rose out and puts it in yours, shutting you up before speaking in an frustrated tone "ive had enough of this." she says as she gives you one painful push before continuing "you will date me." she says as she continues staring down at you, daring you to defy her
