"I have to thank her. She has taught me the meaning of the word "kindness". If this world is filled with people like Mai, so there's no need for humanity to war, because its easy for "us" to invade. (laughs)"

Subtitle: Espionage Alien (諜報宇宙人 Chōhō Uchūjin)
One clear night, a crashed UFO was found on radar. Upon examining the wreckage, Super GUTS found an unconscious alien by the name of Alien Krea Shion. After he recovered, he was interrogated by Super GUTS to see why his saucer crashed to Earth. He revealed that he was attacking a monster named Gyanzar. With Gyanzar appearing in a nearby city, Super GUTS had Shion sent to a medical room for safekeeping. After Gyanzar seemingly disappeared, every member of Super GUTS except for Mai began to see Shion in a negative light. Because of this negative influence, TPC ordered the alien's execution.
That night, Mai, under Shion's control using a control stone, started to try and hack into the computer system. However, this was cut short after Ryo caught him red-handed and forced him to escape. Although his control stone was destroyed, Krea Seijin managed to escape into his saucer and fly off the base. Once Shion summoned Gyanzar to attack Super GUTS's base he went into a one-on-one duel with Ryo. After a short dogfight, Ryo managed to destroy Shion in his saucer, leaving Gyanzar to fend for himself. After Dyna's battle with the monster, Mai whom was awakened from Shion's control was given a lie by Ryo that the alien had returned to it's homeworld, not wanting to hurt her feelings.
