Mayu Hasuda is a minor character in Battle Royale II: Requiem. She is a student at Shikanotoride Middle School who transferred there after her parents divorced. Mayu is described as very healthy, athletic, and bright. She is a gymnast and a tennis player and serves as one of the class representatives. Her closest friend is Risa Shindo, and she is also mutual friends with Honami Totsuka. Mayu is among the forty-two students forced to participate in the new Battle Royale program, which involves infiltrating the Wild Seven’s island base and killing Shuya Nanahara. She manages to survive the extended conflict that unfolds on the island, enduring the chaos, violence, and airstrike that follows. Along with Takuma Aoi, Haruya Sakurai, Nao Asakura, Kyoko Kakei, and Risa Shindo, Mayu is one of the six students who ultimately escape the island alive. Her personal motivations are not deeply explored, but her survival demonstrates resilience and adaptability. She does not possess any exceptional combat or tactical abilities beyond her general athleticism and physical fitness, which likely aid her in navigating the dangerous situation. Mayu does not undergo significant character development on screen; she remains a background presence whose primary function is to survive alongside her friend Risa. Her role in the story is limited to that of a survivor, contributing to the group of students who make it through the ordeal.
