Jima

Roughly matching Child Emperor in age, Jima is a young boy whose exact years are never pinned down. A large nose sits at the center of his face, framed by heavy dark brows and neatly kept black hair. For clothing he favors a pale shirt finished off with a bow tie.

By his own admission, Jima grows jittery whenever he has to speak with Isamu. That nervousness aside, his brainpower puts him on roughly equal footing with his friend, and both rank among the sharpest young minds around. He carries himself with a serious streak and bristles when anyone treads on the things he cares about.

When machines stormed the network during the robot invasion, Jima joined the rest of the Cram School students in reaching out to Isamu, each of them eager to lend a hand. He was especially annoyed that the servers of Ark & Ark had fallen to the same hackers. Isamu urged the children to flee, but Jima and the others turned him down, choosing to stand and fight the robots instead.

He set his own robot army into production and floated the plan of dispatching it to the closest city. Bofoi later revealed to Isamu that he had shut those efforts down, seizing Jima and his classmates as captives. Throughout, the boy's genius-level intellect stands well beyond that of a typical grown adult.
