Miwa Samezu is a first-year literature student at the same university as the protagonist Sakurako Umeyashiki. She is characterized by a bold, confident, and self-centered personality. She is often described as a go-getter who is not afraid to pursue what she wants, particularly her romantic interest in Akihiro Tsurumi. Her approach to him can be pushy and assertive, and she tends to believe her own ideas are always correct. Miwa is highly concerned with appearances and social media, placing great importance on creating visually appealing or instagrammable moments. She is willing to put in considerable effort for the sake of looking good or gaining attention. Despite her strong and sometimes mean exterior, she hides a layer of surprising innocence beneath her confident facade. Her motivations are driven largely by her desire to be the center of attention and her single-minded pursuit of Akihiro. In the story, she serves as a supporting character, interacting with the main group and often creating social dynamics through her self-absorbed and competitive nature. While she does not possess any special abilities, her determination and persistence in achieving her goals stand out as notable traits. Miwa does not undergo major visible development, but her interactions occasionally reveal a softer, more vulnerable side that contrasts with her usual domineering attitude.
