Hajime attends an art-focused high school, possessing a tall, athletic build and initially presenting with short dark hair that leads others to assume a male identity. Hajime's background stems from a family environment preferring sons, resulting in an upbringing as a boy involving traditionally masculine activities like kendo, where Hajime demonstrates exceptional skill. Pressure to conform maintained the short hairstyle and masculine presentation upon entering high school.

Throughout the narrative, Hajime undergoes significant personal development centered on gender identity, questioning the imposed male role and exploring a female identity. This causes discomfort when perceived as male and fuels a growing desire for feminine expression. Hajime's journey involves gradually embracing a female identity, marked by pivotal decisions like growing out the hair—symbolizing rejection of the male role—and adopting the female school uniform. Supportive interactions with accepting classmates prove crucial during this transition.

Hajime remains active in the kendo club, illustrating the separation between athletic prowess and gender identity. The narrative traces evolving self-acceptance as Hajime navigates authentic self-presentation amid societal perceptions and peer confusion over the changed appearance. Hajime exhibits quiet determination, loyalty to friends, and early reserve, later developing a more relaxed, open demeanor as identity solidifies. School friendships provide strength and normalcy throughout the transition.
