Spoiler:
Somewhere between the cracks of time, the seal the Kaiōshin of Time placed around herself and the Dark Demon Realm comes undone. Mechickaboola, undergoing a further transformation from his youthful self, proclaims that the complete revival of the Dark Demon Realm is at hand. All members of Mechickaboola's Demon Gods—Towa, Dabra, Gravy, Poutine, Salsa and Shroom—emerge in new forms similar to Mechickaboola's own, with wild hair and new facial marks. A small figure waits next to Mechickaboola in the distance.
Meanwhile, at the Time Nest, Elder Kaiōshin laments that he came upon sensing disturbances in space-time only to find that the Demon Realm he'd heard of in rumors not only existed, but had already revived. He thanks the Time Patrol for fighting to preserve history up to now. Trunks: Xeno, Goku: Xeno, and Vegeta: Xeno, Gohan: Xeno and Goten: Xeno respond happily.
Trunks: Xeno examines a Time Scroll and notes that it shows some signs of altered history, albeit faint. As it may be the Demon Realm exerting its influence once again, he volunteers to investigate. Old Kaioshin sees the Time Patrol off and tells them to leave taking care of Tokitoki to him (inflecting a Japanese -teoke sentence-ending into -toki, meaning "time," dejectedly commenting that no one reacted to his pun).
Elsewhere, Chamel reports to Demigra to inform him that the Time Patrol has taken the bait. Demigra praises Chamel for his work. Demigra's assistant Robel states that the success of their plan hinged upon the investigation she carried out, and Demigra compliments her as well. The three prepare to head to the scene.
The members of the Time Patrol arrive in the middle of a ruined city and wonder what era they're in. Goku: Xeno notices two incredibly strong ki clashing in the sky above them. Gogeta, in his Super Saiyan 4 state, elbows Yi Xing Long in the face and sends the evil dragon flying into a nearby skyscraper. Trunks: Xeno recognizes Gogeta as the fused form of Goku and his father. Although the battle the Time Patrol is witnessing is incredible, Trunks: Xeno wonders where the temporal abnormality is.
A group of Dragon Ball GT-era characters consisting of Gohan, Goten, Trunks, Pan, Oob, Mr. Satan, Chi-Chi, Bulma and Videl gathers behind the Time Patrol and fires a blast toward them, causing the Time Patrol to scatter. Gogeta notices the scuffle below as Towa says their target has been discovered, commanding a mysterious Majin Boo-like creature to attack. The creature besieges Gogeta, restricting his movement by wrapping him in its elastic arms. Gogeta is interested in what else the creature can do, and asks it to show him some more. It responds by whipping its arms down and slamming him into the ground.
Meanwhile, the Time Patrol is locked in a fierce battle against their GT counterparts. Trunks: Xeno faces his alternate self, while Vegeta: Xeno is stopped from intervening by GT-era Bulma rushing in front of his attack. The two versions of Goten face off, while Goku: Xeno gently knocks out Chi-Chi and Mr. Satan before squaring off against Oob.
Trunks: Xeno confirms his suspicions that their opponents are being controlled. On top of that, with the "dark ki" he can feel, it seems that the Dark Demon Realm may have been released. No sooner does he consider the possibility than he notices Towa and Dabra: Xeno floating nearby.
Trunks: Xeno demands to know how they got free and if the Kaiōshin of Time is okay. Towa tells him not to worry; the Kaiōshin is doing quite well.
Towa says their intention was to not be discovered, but the Time Patrol insists on meddling as always. Dabra: Xeno is happy that this will provide opportunity to test his new power, beginning with a light warm-up. He shifts his sword down slightly, creating a shockwave that tears through the city. Vegeta: Xeno is in awe of how much power Dabra: Xeno produced with such a slight movement, while Goten: Xeno is distraught over the fact that his GT counterpart was caught up in the attack. Dabra: Xeno begins gathering power. Next comes the actual warm-up. A gigantic energy wave bears down on the Time Patrol, stopped at the last moment by one of Chamel's shield spells.
Demigra emerges and tells Robel to return the attack. Robel twirls her wand and invokes "the road that winds through time—Time Rail," a technique which summons multiple circular ruptures in space-time which carry Dabra: Xeno's attack back toward him.
Dabra: Xeno, his shoulder bloodied from being struck by his own attack, recognizes Chamel, Robel and Demigra as members of the Demon Realm's vanished sect. Vegeta: Xeno is horrified by Robel's ability to so easily return Dabra: Xeno's gigantic slash attack, and wonders if this is the level of battles to come.
Gohan: Xeno recognizes Chamel from their earlier team-up, and calls out to him only to be sucker-punched by Pan. Robel steps in and instantly puts Pan and Videl to sleep by tapping her wand to their foreheads. She proclaims dealing with the unexpected obstacles is complete. She asks the Time Patrol to act according to her instructions moving forward.
Trunks: Xeno asks Chamel if he's really working with Demigra. Chamel says Trunks can draw his own conclusions simply from observing the situation. The Time Patrol is as inefficient as ever.
Trunks: Xeno wonders why Demigra would help them, if his aim is to take the Kaiōshin of Time's seat. Demigra says that it looks like Trunks wants to ask about their motives, but that he should pay it no attention. It's simply convenient for them to make use of the Time Patrol.
Robel asks the Time Patrol to move quickly and according to her plan. First, she instructs Goku: Xeno and Vegeta: Xeno to fuse. To Goku: Xeno's surprise, Vegeta: Xeno immediately agrees, having been rattled by the scale of Dabra: Xeno's attacks. Vegeta: Xeno insists, however, that it isn't to follow Robel's plan, but simply a matter of winning. Robel comments that just as she'd discovered in her investigation, Vegeta has absurdly high pride. Vegeta: Xeno shouts at Goku: Xeno to get into position, as Goku:Xeno notes, flustered, that they haven't even had time to align their ki.
Demigra orders Chamel to set a barrier around the group to avoid any interference. Goku: Xeno and Vegeta: Xeno successfully fuse into Gogeta: Xeno, who transforms into Super Saiyan 4.
Witnessing the explosion of energy surrounding Gogeta: Xeno's transformation, Dabra: Xeno tells Towa that if Demigra and the others have allied themselves with the Time Patrol, it may be best to retreat. Towa agrees. Besides, it looks as if they've obtained the power they came for.
From the rubble of a nearby building, the Majin Boo-like creature emerges in a visage recalling Gogeta's wild hair and jacket.
"He has terrifying energy, doesn't he?" Towa says. "My precious Fin."

Differences from the corresponding arcade material:
Spoiler:
- The Dark Demon Realm Mission! manga omits the Demigra Assault Arc entirely, making the team-up of the Time Patrol and Demigra in this chapter their first interaction since Trunks encountered Demigra in Chapter 1.
- Chamel does not appear in the arcade game as a distinct character, being based on the Demon God player avatar. Instead, Chamel's activity in the manga is based on his role in the story mode of the Dragon Ball Heroes: Ultimate Mission X home port for the Nintendo 3DS.
- In the arcade game, Demigra and Robel have already engaged Mechickaboola's Demon Gods and are being driven away from the battlefield when they encounter the Time Patrol.
- Mechickaboola and the other Demon Gods are not present in the GT-era battlefield in the manga.
- In the arcade game, the Time Patrol, the Gogeta native to the GT timeline, Demigra and Robel attempt to defeat Yi Xing Long together to obtain the Dragon Balls, a plot line omitted from the manga.
- In the arcade game, Robel does not suggest Goku: Xeno and Vegeta: Xeno fuse until the group has already begun their battle against the Gogeta-absorbed Fin. Prior to their confrontation, Goku: Xeno and Vegeta: Xeno fuse into Super Saiyan Gogeta to more quickly dispatch the possessed GT-era fighters.
