Powered Suit Guyfant ~A Robot Appears in a Fantasy World?

Junesteen (Junes) suddenly appears in another world as a child.
In a world where he has no memory and no language, he was helped by an adventurer who happened to pass by, learned the language at the guild, and lived in the world as an adventurer.
Relying on the fragmentary memories of his previous life, he incorporated a skeleton into the full metal armor to reduce the burden on the human skeleton, but felt the limits of the equipment and reconsidered the basic concept to develop equipment.

On the other hand, Shurei Noria (Shure), who was transferred the day after Junes, researched the magic in this world from the concept and streamlined the magic itself with its own ideas, raising the power of magic to a level that others could not reach. Conversely, if you can't suppress the power and limit the place and timing of use, you won't be able to use it.

Jeunesse used magic crests to assist driving, but it didn't go well, so he consulted Shure about engraving complicated controls into magic crests. Complete the magic crest drive with control added.
When she succeeded in developing a unique powered suit that had never been seen before in the world by fusing machines and magic, she came up with the idea of hoverboards and hovercraft as new means of transportation during the assembly work.
Her full body armor, artificial skeleton and artificial muscles amplify her physical ability several times, possess overwhelming defensive power, and complete a powered suit with a hovercraft as a means of high-speed movement.

After successfully developing a powered suit, Jeunesse and the others are asked by the Guild, who wants to use its power, to investigate the eastern part of the continent beyond the eastern forest, which no one has ever been to.
However, in order to enter the eastern forest, permission is required from the Great Tu-Bar Empire, which aims to increase its military power by taking in Jeunesse and other adventurers who belong to the guild.
When Unit 1 of Powered Suit Rev.3.00 is completed, he heads for the Empire, but repels the monsters of the Eastern Forest encountered on the way with a powered suit, and waits for permission to enter the Eastern Forest in the Imperial Capital.
In the meantime, if you deliver the remaining five semi-finished powered suits to the empire, complete them in secret and defeat the monsters that appear in the empire.
Hearing rumors about Jeunesse and his companions, the Imperial Army requests Jeunesse and his party to investigate the eastern forest, but at the same time, they plan to take Jeunesse and his companions into the water by the Great Tu-Bar Empire. .
