The Demon Seed reveal there are General Palasts across Japan, and - after using tentacles to kidnap the Army of Idols - take their individual opponents to their specific Palasts.  The General Palast breaks into five pieces, with each Death-Match Room going to the new locations. 
After a hellish battle, Scarface is placed inside Voltman's oven body and burnt to a crisp. A rematch is scheduled, but this time Kevin teams up with Mantaro as The Young Masters (ザ・坊ちゃんズ The Botchans). They are given a few days to train for the match, but instead of sparring with Check Mate and Jade like suggested, Kevin goes off on his own.
The day of the rematch comes and Kevin and Mantaro enter the Demon Womb, fighting in a ring atop hundreds of Chojin corpses, including the fallen Idol Chojin. Kevin dedicates the fight to Scar and focuses mainly on Voltman. As the fight gets underway it soon becomes a handicap match against Voltman, with Kevin receiving more damage than Mantaro. Eventually they are able to defeat Voltman with their combo technique the Niku→Lap. Kevin saves Meat's right leg but then passes out from exhaustion, falling out of the ring and to his death. Later, when Mantaro falls out of the ring, Kevin and the other fallen Idol Chojin souls help him back to the ring.
After Mantaro defeats Ashuraman and Meat is revived, Kevin and the others are revived by the Reborn Diamond. However, as the Demon Womb collapses, Kevin is the only one too exhausted to make it out in time. Kinnikuman then runs it at the last second and saves Kevin, saying that he'd never be able to face Robin Mask again if he let his son die twice

Lightning escapes from Kevin Mask's royal stretch with a four-point sickle impact.  This knocks Kevin outside of the ring, along with Mantaro who was downed by Thunder. They gives the Young Masters time to return to the ring, before they remove their acceleration mouth-pieces, and - reversing them - use the Evolution Mouthpiece Reverse. The Young Masters attempt a Chojin Merry-go-Round, as they attempt to blow away the Exotic Matter from the Five Disasters, but the Five Disasters counter with a Body-Clock Back-Spin. This heals their wounds and they use a Disaster Merry-go-Round.

Thunder holds back Mantaro, while Lightning lunges for Kevin Mask.  Kevin Mask uses a Unicorn Head against Lightning's Boiling Sickle, which breaks off Lightning's sickle and downs him. Thunder becomes triggered by Robin Mask's attention on Kevin Mask, leading to a flashback of his youth, and he begins a series of violent blows on Mantaro. They then use a 12 o'Clock Crash.

Kevin Mask is inspired by the spirit of Ramenman, while Mantaro summons his Fire of Inner Strength.  They combine their Muscle Millennium and Big Ben Edge attacks to create a Muscle Kingdom. This decides the match in favour of the Young Masters.  The Young Masters take the trophy, and the trophy bulbs, and toss two fragments of the bulbs to a downed Thunder and Lightning.  Thunder heals, but Lightning spits out the trophy bulb and proceeds to throw himself into Mount Fuji due to his defeat. 
The Young Masters burn the leftover trophy bulbs, only saving enough to save a few allies: Ramenman, Chaos, Buffaloman, Geronimo, and Brocken Jr.  They proceed to give the trophy to The Machineguns, and then say farewell to their parents, while Thunder uses the last of his Exotic Matter to send the time-ship back to the future. Thunder sacrifices his life, while the New Generation return home.
