Amato and Mechabot were chased by a giant robot which resembles like a green dinosaur. Mechabot said to Amato that the giant dino robot is the most dangerous robot among other robots that have been found with Amato at his robot collection on his cellphone. It didn’t even work with Mechamato’s Mecha Rapid Blaster but it might cause the bullets hit back at Mechamato instead.

Becoming spread out to sea, suddenly the Giant Robot met a tunnel called Sumorai’s Tunnel, which owned by a robot who is obviously been known as a teacher of the giant robot, where he was one of Sumorai’s students. On the other hand, according to Amato’s cellphone, Sumorai turned out to be a giant robot and was once a prisoner robot who was even included as one of the most dangerous robots in the world.

Suddenly Amato and Mechabot meet Uncle Gobi, whose shop is fatally damaged by a mysterious evil robot that destroys it and removes the wall (according to Pian).

According to his testimony and how he witness, the robot has a sword and its really giant, suspected by Amato and Mechabot as Sumorai. Using a scanner, the two of them searched for traces of Sumorai by looking for a signal from the Sumorai. But apparently, it was the cat who became the strongest signal in an alley, and it turned out that Sumorai was located there and immediately ran away, making Amato and Mechabot chase after him even with Mecha-Jumpers.

It turns out that Sumorai allegedly destroyed a lot of things such as splitting two trucks with a sword and threatening every Hilir citizen. Amato and Mechabot find a way to stop Sumorai. However, his irresistible power were told by a stems from a story in the Space Prison Arena that it was said that they release him freely from the prison.

Mechabot then suggests that Amato may able to fight Sumorai. Meanwhile, Sumorai meets the ‘Master Cat’ the Mysterious Cat who turns out to be the cat that Amato and Mechabot had found at the alley. And it also revealed that the story of the shop’s destruction was that he was looking for a cat who turned out to be Master Cat, but Amato and Mechabot still not get it how Sumorai related with that cat.

Mechabot takes Amato and his friends to the Space Prison Arena where they will battle Sumorai. By using the Mechanize Mechamato, he fought the Giant Robot who was said to be ‘strong but scared’. In fact, during the fight, it was revealed that the cat’s name was Oyen Son, which was sadly the adopted pet of Sumorai.

Mechamato uses various methods to defeat Sumorai, by using Mechaninja which is stronger than the previous Mechamato class, to fight with samurai.

The strength of the Mechaninja’s rope makes it more likely that Sumorai will lose this match. Oyen Son is even known to Pian as ‘Sumorai’, which turns out to be Oyen Son as himself.

Oyen Son who was rescued by Mechamato was very worried by Sumorai and he thanked Amato and his friends for saving the pet cat. Then he told to them that the real story started while in Space Military, Sumorai was once a chef and he accidentally set fire to his military arena because of a gas leak and he felt guilty for destroying the Space Military. In the end, as the part of the resurrection and vindication of his former bad and accidental behavior, Amato took Sumorai to Amato’s house as a housekeeper and he cooked some food, even washed and cleaned Amato’s house.
