Mizuki Sera wears multiple hats as an engine engineer in A-TEC and the class representative, while also being the younger sister of their homeroom teacher, Kaito Sera. Having lost both parents at a young age, she single-handedly manages household duties and continues to support her brother. Within the team, her optimistic and nurturing presence acts as an emotional anchor, and her gentle outreach toward the aloof transfer student Nagisa Kiryuu makes her an indispensable bridge connecting all members of A-TEC.
