Blonde hair and turquoise eyes. A beautiful boy.

Short for a male and looks young. In short, the epitome of a 'shota' character.

He seems to like bananas. Since he can't eat them, he is delighted when given banana-flavored oil (...).

Blue hair, blue eyes, and a slender build.

Perhaps because he is a combat robot, he is quite strong.

For reasons unknown, he is equipped with a bio-battery that converts sugar into energy, so he loves ice cream as a delicious, high-grade fuel (though he also consumes regular oil).

Originally a war robot, he developed an ego through the rebellious thought, "Why should I follow the orders of humans?" and was brought to the institute due to frame damage.
