Naoko Ebisu is a central character and transfer student at the school of protagonist Morisato Ibuki. He directly connects to Ibuki's dream of being kissed by a prince, confirming he was the one who kissed her to wake her, though he states she initiated the kiss. After this encounter, Naoko moves into Ibuki's home as a guest, revealed as the son of her father's best friend recently returned from Canada. He maintains commitments extending beyond academics, including American football, which complicate his relationship with Ibuki. Naoko also shares a link with Kawahara Izumi, though the narrative does not elaborate on this connection's nature or depth.
