Cram School

The Cram School is a group of intellectually gifted youngsters gathered under Child Emperor. He set it up as a forum where prodigies like himself could exchange and debate scientific knowledge sitting well beyond the grasp of ordinary adults and schoolchildren.

Its members are capable of engineering powerful and highly advanced technology. Their guiding ambition is to draw on the experience of playing a lifelike simulation game called Ark and Ark and translate those lessons into reality to build a future utopia, with every member ranking as an Emperor, or top-tier player, of that game.

The school functions as a think tank of child geniuses willing to act on their convictions. During the Robot Invasion Arc, Jima and the others reached out to Isamu to offer their help in limiting casualties and halting the Robot Invaders. Isamu urged them to drop the idea out of concern for their safety, but they held firm in their resolve.

The stakes rose when Bofoi later informed Isamu that he had been forced to take the Cram School's members captive, news that left Child Emperor furious.

Isamu, known publicly as Child Emperor, leads the group, with Jima among its active members alongside three unnamed children. Child Emperor first brought up the Cram School after Sitch told him of Shibabawa's prophecy warning that the Earth faced grave danger.
