Scalding Battle!! Gravion Hot Springs!!.Sandman is taking all the maids and pilots on a trip to a hot springs resort, as the annual Earthgertz trip. Raven ruminates about how irritating it is that they cannot do anything until the Zeravire show their face again, refusing to go to the hot springs with the rest. Eina is shy about going into the hot springs, and Mizuki drags her in. Eiji and Toga relax in the hot springs when some of the castle maids show up to wash Eiji. Struggling to get away, Eiji breaks through the wall of the hot springs and slides down the mountain, with Toga following. Eiji and Toga run through the women's bath, annoying all the girls. Alex Smith, Faye and the G-Soldiers arrive, just as Toga and Eiji slide in. Eiji and Toga are out in the town at night, and see Sandman on a bridge with a man who claims to be his brother. The ground is rumbling, as the Zeravire is drilling inside the mountain. At the hotel, they are playing table tennis, and Alex and Mizuki win against Eina and Luna. Sandman, along with Leele, then challenges Alex and Mizuki to a game to win the hot springs ticket as the prize. He plays with just his shoe instead of a racket. Sandman beats them, winning all rounds. The ground continues to rumble, as the mountain erupts. Gravion enters the volcano, but they only have ninety seconds due to the extreme heat. The maids sing to encourage the Gran Knights. Gravion intercepts the Zeravire pulling it out of the volcano and destroying it. Faye is awestruck by seeing Gravion for the first time. The crew gives the hot springs ticket to Raven, as a way of thanking him for staying at Sandman's castle while they had enjoyed their time at the hot springs.
