A genius with a sharp tongue. He is taciturn, twisted, and a tsundere (90% tsun). He can be vile, trashy, and a total scumbag, yet he is a beautiful boy. He loves experiments to the point of addiction. Constantly sleep-deprived, he doesn't eat proper meals, surviving instead on energy drinks and supplements. He mostly shuts himself away in his laboratory. If he deems someone's actions dangerous, he will splash them with chemicals or forcibly administer drugs. Despite his cruelty, he is extremely sensitive to pain and hates it. While he finds it fun or feels nothing when using test subjects or others for injections, he absolutely loathes being on the receiving end. He prefers bitter flavors over sweet ones. He is an incredibly picky eater. Surprisingly quiet? First person: I (soft, polite).
