Lore & Background

Chiyoda High School is where the central relationship of the series unfolds. It is here that Aya Osawa, an extroverted gyaru with a passion for rock music, interacts daily with her aloof classmate Mitsuki Koga, unaware that Mitsuki is the same person as the masked record store clerk she has a crush on, whom she calls "Onii-san." The school setting is crucial for the series' dramatic irony, as Aya confides in her friends Chizuru and Mao about her feelings for Onii-san, all while Mitsuki sits nearby, listening. It is also where Megumu Narita, a friend and classmate, becomes the first person to deduce that Mitsuki and Onii-san are the same person, after noticing their similarities. The school provides the mundane, everyday environment where the two girls navigate their friendship, with Mitsuki taking measures to prevent Aya from figuring out her secret identity. Ultimately, it is within this setting that their connection deepens, leading them to begin dating.

In Their Own Story

The classroom buzzed with the usual pre-lesson chatter. Aya leaned over to Chizuru and Mao, her voice a conspiratorial whisper. "I'm going to the record store again today. I hope Onii-san is working." Across the room, Mitsuki kept her eyes on her desk, her expression unreadable. She had heard everything. Later, in the hallway, Narita fell into step beside her. "You know," he said quietly, "you could just tell her." Mitsuki's only response was a slight tightening of her jaw. The bell rang, and the ordinary school day resumed, the secret hanging between them like a held breath.

Reader's Guide

Chiyoda High School is the central civilian setting for the series, serving as the stage for the daily lives of Aya Osawa and Mitsuki Koga. It is where they attend class as classmates, interact with their mutual friends, and where the central dramatic irony of the plot plays out. Aya, unaware that her crush Onii-san is actually Mitsuki, frequently discusses her feelings with her friends Chizuru and Mao within the school's halls. This forces Mitsuki to constantly maintain her aloof facade to avoid revealing her double life. The school is also where Megumu Narita, a perceptive friend, first connects the dots between Mitsuki and the record store clerk, becoming a key supporter of their relationship. For fans, Chiyoda High represents the normal, everyday world that contrasts with the secret world of the record store. It is the place where Aya and Mitsuki's friendship is tested and ultimately deepens, providing the foundation for their romance to blossom away from the prying eyes of the store's other customers.
