Heidayuu comes from a martial arts family and has the personality to match—decisive and stubborn, with a mischievous streak and a cynical outlook. He's known for being blunt to the point of rudeness, which doesn't always work in his favor.
What sets him apart is his obsession with traps and mechanics. He's genuinely talented with anything involving machinery or engineering, and people recognize it. His shared room with Sanjirou is basically a workshop at this point—packed with devices and traps they've rigged up together. He even managed to convince the Headmaster to let him build an entire underground chamber beneath their dorm, which he's turned into his personal workshop and laboratory.
