Male. He has a somewhat serious and prickly personality. His head is an M870 shotgun. Because his head is a shotgun, he is a pitiful fellow whose head is frequently ripped off by his friends. Unusually, he remains alive even when his head is torn off; it has happened so often that it's become part of his daily routine, so he just shouts "My head!" without much concern.

Male. He has a reptilian appearance, is somewhat thin(?), and possesses incredibly beautiful feathers. He has the horizontal pupils characteristic of goats, walks on all fours, and has sharp spikes(?) at the ends of his legs. His personality is likely quiet and quick-witted.

Male. His appearance is that of a stickman. He has a mischievous streak and loves to startle others. There is a hint of madness in his way of speaking. Even when facing Alice, the strongest in the school, he doesn't get scared and instead just laughs.

Gender unknown. His torso consists of an old computer monitor with a gray frame, displaying a large purple-drawn mouth. His head is a small monitor detached from the body, appearing to float with blue electricity connecting it like a neck. The head screen displays one large eye, and several long, thin antennas extend from his back with round metal devices at the tips. A black cable with a power plug hangs from one side of his torso. His legs are not normal; the right leg flows with green electricity, the left with red electricity, and blue electricity constantly flows through his neck. When he speaks, he uses a slightly distorted male voice and can only say two phrases: "Loading Error" and "Please try again."

Male. His head is a human arm with a single eye on the back of the hand. His torso is a box(?) with a window, and wheels for movement are attached to the bottom. He plays the electric guitar as a hobby, but he is so bad at it that students who hear the sound all cover their ears. He is the most skilled in engineering after Edward and Robby. He has a somewhat intelligent yet fastidious personality. He seems to be plotting something suspicious at the school.

Female. Most of her body is white, she wears a white skirt, and she is a white cat beastman(?) with cat ears. The letter 'N' is written on her chest. Both arms are very long and uniquely shaped, and her legs end in sharp points. She has a very pure and cheerful personality. She engages in various suspicious behaviors, such as hanging around with Pop.
