Tobari Haneda is a female student in the class for demi-humans, known for her cool-type gyaru demeanor and her identity as a shrike, a type of bird also known as a butcher bird. Her birthday is on November 3rd. Among her peers, she stands out as a caring and reliable individual who naturally takes on the role of class organizer, looking after others and helping to keep the group in order.

Despite her composed and fashionable exterior, Tobari holds a significant personal ambition that defines much of her character. She openly expresses a desire to become a human, a goal that is not merely about changing her species but is specifically tied to her passion for music, as she wishes to pursue a musical path that she feels is only possible as a human. This motivation gives her a unique perspective among her classmates, as her view of humanity is layered with both aspiration and complexity.

Her role in the story is highlighted by a recurring and mysterious condition that she experiences annually. At a certain time each year, Tobari suffers from a physical collapse, a period of illness that is not an accident but a predictable part of her life, likely connected to her nature as a shrike demi-human. This periodic ailment brings her into a deeper interaction with her homeroom teacher, the misanthropic Hitoma Rei. When she falls ill and is resting in the school's infirmary, the teacher comes to check on her, leading to a significant conversation between them. During this exchange, she asks the teacher questions about his life, which not only touches on his past trauma as a human educator but also reveals her own profound contemplations about her goal of becoming human. This interaction serves as a key moment for both characters, forcing the teacher to confront his closed-off heart while shedding light on Tobari's internal struggles. Her development in the narrative revolves around the revelation of this secret and the deepening exploration of what her wish for humanity truly entails.
