Tulia Kaido joins National Team B for Olympic training alongside Mila Hazuki and Nami Hayase. Demonstrating considerable volleyball skill, her approach simultaneously disrupts team dynamics through apparent arrogance and rudeness, creating friction that negatively impacts Team B's harmony during training and matches. Tulia later transfers to National Team A in an exchange involving Maomi Masuda, placing her opposite her former teammates. Her strong performance continues, particularly noted in inter-squad friendlies between the national teams. Despite her competitive nature, Tulia undergoes significant development. Following these friendlies, she acknowledges her past mistakes in attitude and conduct, leading to reconciliation with Mila Hazuki where Tulia explicitly admits her faults and establishes a friendship.
