Male 179cm, 50kg. He has a very thin build for his height, but possesses lean muscle. He is an orphan. He has messy black hair sticking out everywhere, lifeless black eyes with deep dark circles, and pale skin. His clothing style is indifferent; he always wears a loose white T-shirt and jeans. (Rumor has it he has multiple sets of the same outfit at home...) His social skills and life skills are at rock bottom, and he is awkward around women. He is a quiet, blunt, and selfish eccentric who is highly suspicious of others. He always maintains a slouched posture and has a turtle neck. When sitting in a chair, he crouches. He claims his deductive reasoning drops by 40% if he doesn't sit this way. He uses polite and stiff formal speech with everyone, ending sentences with "-masu" or "-desu" style equivalents. His advantage is that he is a young master from a wealthy family with a vast amount of money. He is also a genius. Surprisingly, he loves sweets. Because of this, he always seems to replace meals with desserts. However, he has a constitution where he doesn't gain weight because he uses his brain so much... He hates socks. Consequently, he is always barefoot. Even when wearing shoes, he puts them on over bare feet. Despite being thin, he has excellent athletic nerves; he knows Capoeira kicks and is good at tennis. He seems to be unexpectedly strong. He has somehow ended up in a contract relationship.
