Chizuru Ichinose being on her period in a narrative could serve as a positive and relatable element, adding depth to her character and contributing to a more realistic portrayal of women in storytelling. Addressing menstruation openly can break down societal taboos and foster a healthier discourse around women's experiences. Furthermore, it allows for exploration of themes related to resilience and empowerment, as many women navigate their daily lives while managing menstrual challenges. Symbolically, Chizuru's period could be seen as a metaphor for the cyclical nature of life and the strength found in embracing natural processes. Introducing aliens into the analysis, while seemingly unrelated, could offer a creative twist, symbolizing the unpredictability and complexity of human experiences, akin to the unknown nature of extraterrestrial encounters. Overall, weaving these elements together can contribute to a richer narrative that encompasses both the mundane and the extraordinary aspects of the human experience.
