Episode 6
The plane crash lands to the ground below. Fortunately for the group there was no major damage, and they just needed to lighten the ship's load, leaving behind half of the supplies. As Panzy gives the ship a once-over, she recalls Goku calling Shin a Kai. Goku tells her about the Kais of their world and that Shin is the Supreme Kai. Panzy is amazed but confused that Kais don't get paid for their work. Suddenly, Goku feels the need to defecate. Panzy throws some toilet paper at him as he goes to the bushes. Glorio notices a Gendarmerie plane flying overhead. The officers in it fly down towards them. Glorio says to play along and try to avoid conflict. The officers ask the group what world they're from. Glorio says he's from the first, Shin says he's from the second and Panzy begrudgingly reveals the collar on her neck, signifying she's from the third. The officers ask if they've seen Goku, and Glorio lies, saying they haven't. Satisfied, the officers leave right as Goku returns from the bushes. With the plane fully functional, the group continue flying. Panzy asks Shin if Glind are really born from trees. Shin confirms this, stating that there are five in total and that Glind who are born from the same tree are "siblings", such is the case with Degesu and Arinsu. Unlike the other Glind who left, Degesu stayed behind because he never got along with the rest of his people, whereas Arinsu preferred living in the Demon Realm. Goku comments that all of Shin's siblings seem problematic. As night falls, Panzy offers to take a turn at piloting the plane, but Glorio decides it's best for them to rest for the night instead. He plans on finding a cave for the group to sleep in. Later, Glorio uses some Gomah-branded matches to start a fire as the group have a late-night snack before heading to bed. Goku falls asleep first while the rest have a chat. Panzy asks if Glorio was really from the First Demon World, which he confirms stating that he was hired for work there. Panzy wonders who hired him, but Glorio shuts down the conversation. Shin asks Glorio why he wants to defeat Gomah, with the mercenary responding that Gomah makes Majin suffer. Shin comments that he has a strong sense of justice. Later in the night when everyone else has fallen asleep, Glorio steps outside to contact his employer Arinsu. He updates her that the things are working out, and they should arrive to the First Demon World in a few days. Arinsu requests that Glorio contact her if anything happens. In the early morning, Shin and Glorio are awakened by trembling footsteps and a smelly stench. Goku and Panzy are woken up as a giant Minotaur arrives, and roars at them. Goku is undeterred, thinking the Minotaur is a cow. The Minotaur, who can speak, suddenly gets defensive. Glorio offers to take on the Minotaur, but Goku chimes in saying he'll fight it. Glorio thinks Goku is being arrogant, believing that he's stronger than him. Goku and Glorio end up having their own sparring match to decide who gets to fight Minotaur. Everyone steps outside the cave. Panzy and Minotaur are confused at the events going on, while Shin watches intently. Goku ups the ante by stating he'll fight using only one arm. The battle begins with Goku and Glorio trading blows and dodging each other's moves. Glorio deploys another tactic using his own magic. Goku watches as Glorio lifts his ring finger and a white ball of energy emerges with purple thunder starts to spark from it. He launches the attack as Goku dodges, leaving a smoking crater in the ground. Shin yells to Goku that he must fight more seriously, and that he wants to see powerful Glorio is. Goku agrees to this, disregarding his earlier "one-arm" fighting condition, and brings out the Power Pole. Goku flies towards Glorio, dodging all of his lightning blasts. The Power Pole extends, hitting Glorio in the stomach and sending him flying into a nearby rock-face. Glorio responds, launching another more powerful blast which knocks the Power Pole out of Goku's hands. As Glorio charges an even stronger blast, Goku screams as he attempts to fully transform into his Super Saiyan form. Goku fulling taps into the Super Saiyan power as Glorio fires his blast, but Goku effortlessly blocks it with one finger. Goku teleports behind Glorio, putting his hand behind his back. Glorio gives up, stating that Goku wins and asks if Goku has any other special skills, while Panzy is stunned by the display, mistaking the Super Saiyan form for magic. Minotaur tries to sneak away, but Goku notices, stating that he's ready to fight now. Intimidated, Minotaur says that he already ate a beast the night before and retreats back into the cave. The group prepare to take their leave, but Goku needs to poop again. Back on Earth, Vegeta is lifting weights as Bulma finishes repairing Shin's plane. Vegeta, Piccolo and Kibito prepare to leave for the Demon Realm, with Bulma and Mr. Popo seeing them off. But the ship's alarms go off and the lights on it go red. The ship crashes back down to the Lookout.
Episode 7
Goku and his companions continue their journey. But the Gendarmerie appear and bar their way again, perhaps due to them knowing the location of the Magic Collar around Panzy's neck. Can the bond with her friends save Panzy from peril?
