Yuka returns home as her sister is knocked down by a car. Yuka finds her, but is blamed for the accident and is kicked out of the house. The next morning, Mari finds Keitaro and the Faiz Gear gone. He intends to use it to realize his dream of protecting people but is attacked by the two Orphenochs. He tries to use the Gear, but it won't work for him. Takumi and Mari arrive as the Cactus Orphenoch becomes Faiz. Yuka transforms into the Crane Orphenoch and kills her school gym class. Faiz kills the Mantis Orphenoch, but when he goes to attack Mari, the Auto Vajin motorcycle transforms into a robot to protect her. It defeats Faiz, allowing Takumi to recover the belt and kill the Orphenoch. Takumi finally agrees to keep the belt as Yuka meets Yuji.
