Ultraman X S01E07 - An Oath That Surpassed the Stars

As Xio, Ultraman X and Rudian fight Gargorgon, the monster attacks Rudian but X sacrifices himself to protect him and tE-rU, thus the Ultra was petrified. On space, Gargorgon demanded Earth to surrender tE-rU in 44 minutes or else all lifeforms will be petrified. All nationwide branches of Xio launch several missiles, only to be destroyed easily. tE-rU provides his aid to Xio and they work on a plan to attack Gargorgon's main eye to restore X. Eventually, as it seems that tE-rU would nearly costs his own life, Xio members manage to destroy said organ, saving the Ultra, tE-rU and Rudian. Equipped with the Bemstar Armor, X redirects Gargorgon's attack, petrifying her and for Rudian to kill the destroyer. As Xio member celebrates, tE-rU reconciles with Yuuki, the schoolgirl from earlier and gives her his pendant before returning back to his homeland. Daichi swears that one day, Earth and Planet Gold will be united in spirit.
