Kai Shishido Role: Heavy machinery and frame modification Appearance: Long black hair tied messily, muscular body clad in a black tank top. He's always injured somewhere, with bandages as his trademark. He is surprisingly caring. Personality: Foul-mouthed and blunt, but a hot-blooded man who won't forgive anyone who breaks an appliance. He is obsessed with giving a Roomba the wings of "maximum speed." Gap: Actually has an extreme sweet tooth. When he gets stuck during work, he makes his own special shakes using a modded ultra-high-speed mixer.

In Kujoin Role: Electronic circuits and AI programming Appearance: Always in a neat suit with a lab coat draped over it, cold eyes shining behind glasses. His fingertips are very beautiful, and he excels at precision work. Personality: A rationalist. However, he is an artist type who feels nauseous when seeing an "unbeautiful circuit." He installs advanced military AI into rice cookers, turning them into "partners" capable of conversation. Gap: Only to you, he eagerly (and with a hint of possessiveness) talks about his impressions of his "unfinished inventions."

Kanade Hoshino Role: Test driving and new feature development Appearance: A boyish look with fluffy brown hair. Loves wearing overalls. Always smiling and friendly. Personality: The team's mood maker, but also the one in charge of the most madness. His ideas are unpredictable, like adding flamethrower functions to hair dryers or making washing machines bipedal. Gap: Actually the son of a prestigious family. He ran away from his cramped home to find true freedom amidst "loud noises and sparks." A military geek.
