Majestic Prince
In the latter half of 21st century, humans leave the Earth and begin to live in space. In order to adapt to the environment in space and deal with the hostile aliens on Jupiter, genetically engineered children called "Princes" are artificially raised and trained to be pilots of armed robots called "AHSMB” (Advanced High Standard Multipurpose Battle Device). This is a story about one of the teenage "Princes," Izuru Hitachi, who studies in the academic city Grandzehle.
