Episode 12 of "Dragon Ball Daima" kicks off with an intense confrontation as Goku squares off against the Krakken, a monstrous beast that had apparently devoured Vegeta. Goku's sharp eyes catch sight of Vegeta dangling precariously from one of the Krakken's colossal tentacles, engaged in relentless combat with Tamagami Number Two. Just when it seems Vegeta might be swallowed by the beast once more, he gathers his strength to burst free in a burst of power, only to watch the Krakken retreat from the fray.
As Vegeta and Two's battle intensifies, the narrative shifts to Majin Duu's fierce duel with Tamagami Number One. Amidst the clash, Duu takes a momentary pause, pleading with Dr. Arinsu for a chocolate treat. Obliging his whims, Majin Kuu dashes off to procure the sweet indulgence.
Elsewhere, Neva, keenly observing the battle, notices Two beginning to falter against Vegeta's relentless assault. In a swift motion, Neva enchants Two with a mysterious ritual, granting him the edge he needs to turn the tide against Vegeta. Meanwhile, Duu continues his strategic evasion from One's relentless pursuit. Degesu and Gomah, watching the unfolding battles from a hidden vantage point, remain puzzled over One's opponent's identity.
Kuu returns, presenting Duu with the requested chocolate, which seemingly rejuvenates him. Empowered, Duu unleashes a series of energy attacks that wound One severely. Degesu zooms in on the footage, revealing Arinsu's presence to Gomah and Degesu, who are now left questioning Arinsu's true intentions.
Defeated, One issues a peculiar challenge to Duu, Kuu, and Arinsu: a mental arithmetic puzzle that must be solved. With the stage set for an unexpected twist, the episode teems with anticipation as the battle dynamics shift once more.
He imparts to Duu the urgent task of summing the myriad numbers ensconced within his enchanted yellow sphere. Kuu, with a hush of confidence, reveals the solution to Duu, who then confidently pronounces the answer. In reward, a hand bestows upon Duu a Dragon Ball, which he promptly entrusts to Arinsu. The trio of Arinsu, Duu, and Kuu then set forth on their journey.
Degesu endeavors to assure Gomah that Arinsu's quest to assemble the Dragon Balls stems from a noble intent—to safeguard them from the encroaching threat of Goku and his comrades. Gomah, however, harbors suspicions, suggesting that Arinsu harbors her own, ulterior motives for collecting the orbs. Meanwhile, Degesu inspects the Demon Realm's second Dragon Ball, alongside Gomah, as they witness the fierce battle between Vegeta and Two.
Vegeta, pushed to his limits by Two's formidable prowess, undergoes a transformation—manifesting as a Super Saiyan 3, a testament to his relentless solo training, as Bulma verifies. With a decisive victory, Vegeta overcomes Two. As a challenge, Two posits a mathematical riddle to Vegeta, who, with unerring precision, solves it and claims Two's Dragon Ball as his prize.
Our heroes then set their course towards Hybis's realm. Glorio, upon inspecting the aircraft's engine, declares it inoperative, casting a pall of concern over the group. Panzy, with her mechanical prowess, takes charge, diagnosing and swiftly repairing the engine. With the plane now functional, she and her compatriots embark on their voyage to the first Demon World. Degesu and Gomah, from their vantage point, keep a vigilant watch, fully cognizant of the heroes' destination.
The episode culminates with Gomah revealing to Degesu a cunning plan, his eyes gleaming with intrigue and anticipation.
