After surviving an accident, she gained the ability to freely control biological currents and transform into Mask United. However, Mask United faces the cost of transformation - after the battle, the intense desire to control Mika occurs. During the fight against KAIJIN, United's desires go out of control due to excessive use of their abilities. He fights while holding back his hot body, but his body is played with by the enemy.
