A new Majin is born in the 9th episode of DBD. The episode starts with Goku, Shin, Glorio & Panzy still flying via the Gendarmerie airship. After Panzy yawns, Glorio figures they should rest now but Panzy becomes annoyed when Shin points out they should set up camp in an obscure area because she wants to bathe & sleep in an actual bed. To make sure others won't recognize Goku as both the one the Gendarmerie are looking for and the one who obtained the Demon Realm's 3-Star Dragonball, Panzy puts a hat on Goku's head to hide his distinct haircut and Glorio figures Panzy's idea for a disguise will suffice.
Goku's group lands in a town on a floating island, shortly afterwards. Glorio points out that Goku should leave the Power Pole on the Gendarmerie airship because its part of the description the Gendarmerie gave in their search for Goku while Shin points out they should keep the Demon Realm's 3-Star Dragonball hidden while out in public which leads to Panzy storing it within one of their many bags. After entering the hotel, Glorio tells the others that he'll order a room for all of them to share as well as room service for the sake of being cautious. After Panzy comments how lucky they are that Glorio has enough money for such accommodations, Shin admits he thought Kadan would be covering the financial aspects of their quest which leads to Panzy explaining that her dad isn't willing to spend more than necessary, especially not until Gomah has been defeated.
Unfortunately, Goku takes off the hat he is supposed to wear as a disguise due to it making his head itch and Shin & Panzy don't realize this until after 2 nearby demons see Goku before Panzy forces the hat back on him. The 2 demons note that Goku matches the description of the one who defeated Tamagami 3 and piece together that the Demon Realm's 3-Star Dragonball is in the bag he's carrying which leads to them planning to steal it in the hopes of selling it for a lot of money. Later on in the night, Panzy finishes taking a bath and insists Goku take a bath too while assuring him he can borrow some of her clothes for the night until his usual outfit is cleaned. After Goku finishes his bath, he sees that room service has provided a lot of food and he's all too happy to start eating…while the bag with the Demon Realm's 3-Star Dragonball remains nearby.
Suddenly, a blue werewolf causes trouble in the hotel's lobby which causes Goku's group to leave their room…which leads to the werewolf whistling and the yellow bird demon breaks through a window to fly off with the Demon Realm's 3-Star Dragonball. Glorio realizes too late that the werewolf was causing a distraction so the bird demon could steal the bag…but Panzy reveals to the others that she placed a tracker on the Demon Realm's 3-Star Dragonball in case of an emergency. Outside a cave above the hotel, the bird demon meets up with the werewolf who transforms back into the blue demon with the white Mohawk to gloat about their successful plan…only to be surprised when Goku finds them shortly afterwards. The thieves try to escape but in the end, Goku manages to reclaim the Demon Realm's 3-Star Dragonball and Glorio uses his magic to throw the thieves into the sky.
Goku & Glorio return to Shin & Panzy with the Demon Realm's 3-Star Dragonball and Glorio offers Panzy a fist bump while complimenting her for coming up with the idea to use a tracker and Panzy returns the fist bump. Not long after, Panzy finishes a call with Kadan and lets the others know about the plan to meet up with the trio being guided by Hybis somewhere near Sir Warp. Glorio asks Goku if his friends are strong enough to "hold their own in a fight" and Goku confirms that's the case for 2 of the 3 (Vegeta & Piccolo) which Panzy admits she finds "scary". To avoid any possible future thefts of the Demon Realm's 3-Star Dragonball, Goku decides to stand guard for the night while the others sleep…only to end up falling asleep eventually although Shin points out that the Demon Realm's 3-Star Dragonball is still safe by the time morning comes. Seeing that no one else was willing to try to steal the Gendarmerie airship in the night, Goku's group are able to take off without any problems and Glorio mentions that it should only take them about a day to get to Sir Warp using the Gendarmerie airship.
Meanwhile, it's revealed that Vegeta, Piccolo, Bulma & Hybis spent the night in another town…and the group wake up to find their airship is missing. Hybis immediately figures out that it was stolen and he suspects that it was probably stolen by the group of demons that picked a fight with Vegeta in the town's bar last night after he accidentally bumped into one of them; a flashback of this incident is shown in the form of Vegeta remembering the events of last night. Hybis thinks to call Panzy so that her group can pick up his group and even suggests a way to pass time with a game…that involves taking out Zombies in the nearby "Zombie Forest" with the risk of being turned into a Zombie. After declining to play the Zombie Game, Bulma takes notice of the eyeball in Hybis' belt buckle and he explains that he found it in the mountains of the Demon Realm's 3rd World years ago.
Back in the Demon Realm's 1st World, Gomah & Degesu are inside the office of the Supreme Demon King's Castle when Degesu is calling the Gendarmerie. After the call ends, Degesu admits to Gomah that some of the Mortals that were turned into kids have succeeded in entering the Demon Realm and Gomah immediately suspects that they're trying to rescue Dende. Degesu also admits that he was informed via the call that the Z-Fighters are trying to collect the Demon Realm's set of Dragonballs which Gomah isn't worried about…until Degesu admits that reports confirm that Goku successfully obtained the Demon Realm's 3-Star Dragonball. When Degesu meekly mentions his hunch that the Z-Fighters are planning to head to the Demon Realm's 2nd World next, Gomah demands that Degesu think of a solution before grumbling about he should've used the wish to obtain the Evil 3rd Eye/Tertian Oculus.
Back in the Demon Realm's 3rd World, Vegeta senses Goku's energy signature as the Gendarmerie airship lands in the town. Bulma & Panzy quickly introduce themselves while Panzy is also surprised to see a Namekian for the first time via Piccolo and Piccolo explains to Goku that Kibito is helping Mr. Popo watch over Kami's Lookout. After Goku confirms having the Demon Realm's 3-Star Dragonball, Vegeta wants to head off…but Goku explains that the Gendarmerie airship doesn't have enough room for more passengers and Glorio isn't willing to remove their cargo to try to make more room. Panzy offers to call Kadan to have another airship sent out (while admitting it'll take some time) while Shin can only apologize for the inconvenience before Goku's group leaves.
Shortly after Goku's group leaves, the group of demons that picked a fight with Vegeta in the town's bar last night arrive to pick another fight with him and even brought more of their friends as backup. After the group of demons confirm that they did steal the airship with a "mid-size passenger load", Vegeta responds that he gets to "unload [his] travel stress" on them and he proceeds to easily beat up the group of demons with Piccolo helping out a little; the group of demons apologize and reveal that the airship is hidden "nearby". Back in the Demon Realm's 1st World, Marba decides it's time to add 1 of 2 Saibamen seeds she has left to the contents of the cauldron that was poured into the stone outside her house and she instructs Arinsu to plant the Saibamen seed only 5cm (1.9685 inches) into the contents of the cauldron out of concern that planting the Saibamen seed deeper would make Buu's essence more prevalent which could lead to this new Majin being harder to control. After the Saibamen seed is planted & watered, the new demon is fully created with Marba describing him as "concocted from various monsters with the Saibamen serving as its base finished with a splash of Majin Buu's essence" and dubbing him "Majin Kuu"; Kuu's design could be described as looking like a fusion between Kid Buu & a Saibamen. Arinsu immediately instructs Kuu to challenge Tamagami 1 and obtain the Demon Realm's 1-Star Dragonball; Marba is surprised by this but Arinsu insists that Kuu has "no reason to exist" if he isn't powerful enough to challenge the Tamagami. The episode ends with Kuu (voiced by Gerard Caster) responding to Arinsu's instructions with "Orders acknowledged".
Overall, this episode focuses on the aftermath of Goku obtaining the Demon Realm's 3-Star Dragonball which includes Gomah finally catching wind. Although the 2 groups of Z-Fighters in the Demon Realm have reunited it's short lived due to the larger airship being hidden until after the reunion. Bulma taking note of Hybis' belt buckle looking like an eyeball reinforces my guess that it'll turn out that Hybis has the Evil 3rd Eye/Tertian Oculus. Some more lore is revealed in the form of Saibamen seeds originating from the Demon Realm and Marba being able to make some cash on the side by selling them to buyers from the Mortal Realm. While this new lore does tie into the Saibamen having pointed ears, I find myself preferring the original explanation of the Saibamen being created by Saiyan Scientists as it helped to show how the (Universe 7) Saiyans' society had more going on beyond just being battle happy and the idea of most things originated from the Demon Realm is starting to remind me of how the Ben 10 Franchise's "UAF Era" had a tendency to have most things have alien origins.
