Jun Yabuki

Jun Yabuki is recruited to replace the fallen Mika Koizumi as Yellow Four. Before joining Bioman, she was training as an archer for the Japanese Olympic team, and the decision to fight Gear forces her to choose between her Olympic dream and her duty to protect Earth.

Jun brings elite marksmanship to the team and adds the Bio Arrow to the Yellow Four arsenal. Like Mika before her, she is an action-oriented fighter who often throws herself directly into battle.

Her combat style emphasizes movement, precision, and athletic courage. High leaps, falls, cable swings, and acrobatic maneuvers show that Jun is a fearless warrior who fully earns her place on the team.
