Ultraman X S01E13 - The Sword of Victory

Mold Spectre kidnaps Show/Ultraman Victory and Arisa (accidentally) to Ultraman X's world as Guar Army's prisoner due to being the murderer of his brother, Juda Spectre. Fortunately, thanks to Arisa, she managed to gain help in the form of UPG, as well as Ultraman X with Show escaped custody and reunited with her. Seeing Daichi's poor swordsmanship, he trained the boy and finally approved his effort. With the Guar Army planning to harvest the Dark Thunder Energy to strengthen their group, Xio, UPG and the Ultramen attacked them, with Exceed X and Victory Knight managed to overpower Mold Spectre and kills Alien Magma. Ultraman Ginga appears to join the fight, having killed the arriving Guar Army's remaining armada
