Jun is a new character introduced in the second season of the series. As a former Takarazuka star, she is portrayed as a legendary figure within the lesbian community, described as a rival to both Hiroko and Kyoko. Jun has been living in Los Angeles for many years before returning to visit a familiar lesbian bar, which becomes a key location for her reintroduction into the story.

Personality-wise, Jun is characterized by an almost mythical level of charm and allure. She is said to possess a captivating gaze, with the reputation that any woman who meets her eyes will fall in love with her. This ability defines her interactions and makes her an immediately significant presence, suggesting a confident and possibly enigmatic demeanor. Her role in the narrative is primarily as a catalyst for conflict between the main couple, Ayaka and Hiroko. Due to her reputation and past history as a rival, Hiroko misinterprets the nature of Jun's relationship with Ayaka, which creates a major obstacle for the central romance.

In terms of story relationships, Jun serves as a figure from Hiroko's past, positioning her as a direct romantic rival. Her arrival challenges the stability of Hiroko's current relationship. Jun also has a connection to Kyoko, as she is named as a rival to her as well, indicating a shared history among these characters. Her key relationship, however, is with Ayaka; the misunderstandings that arise from Hiroko's jealousy over Jun’s interactions with Ayaka form the core of her impact on the plot.

Jun’s primary notable ability is not a physical or professional skill but her immense, almost supernatural personal charisma. Her reputation for making any woman fall in love with her upon meeting her eyes is treated as a legendary trait within the story's world, making her a formidable presence capable of disrupting established relationships without any overt action.
