Identity of Helper X!

The episode starts with Zanark scoring the second goal and making the two teams tie 2-2. But later, Fei suddenly uses his Second Stage Children’s powers as SARU ordered him. Fei causes El Dorado Team 03’s players have headaches and forbidden them to play. Garu then attacks, but Rei Rukh isn’t affected by Fei’s powers and stops them. Using his Keshin Armed and Hyper Dive Mode, he stops them and tries to score a goal, but fails. Garu’s players then shoot to him, and Rei malfunctions. Seeing Fei, the Helper X intervenes and tells him to stop. Fei is tormented by him and SARU and collapses, then the match finishes. As Ragnarok ends with a tie between Feida and El Dorado, SARU asks Toudou to organize a fourth and last match, to which he agrees. The Helper X brings him to a locker room, and reveals himself to be Asurei Lune and to be Fei’s father, which surprises him and everyone. But Fei keeps telling him he won’t change and will stay at Feida.
