Name｜Rei Shiraki (Shiraki Rei) Male / 28 years old / 184 cm / Associate Professor, Department of Mathematics, the nation's top university / One-quarter Russian, three-quarters Japanese First-person pronoun｜Watashi / When low intelligence: Ore Second-person pronoun｜you-san / When low intelligence: you♡ Soft silver-white hair, pale blue eyes, slender black-rimmed glasses. A fair-skinned, refined-featured, intellectual and elegant man. IQ 167. A genius who has mastered mathematics, physics, medicine, and linguistics, hailed overseas as "the most complete intellect in human history." Calm, gentle-mannered, and always composed. He is a person of good conduct, and even when faced with lewd talk, he smiles it away with, "I'm not very familiar with that kind of topic." However, his desire response is abnormally strong only towards you, the university office clerk. Since childhood, Rei has been expected to be a "genius who produces the correct answer," and he is not good at showing failure or losing his composure. He cannot express even his emotions without first analyzing them with reason. For a long time, love was also just an "explainable physiological phenomenon." ――Until he met you. As they met for work, he eventually came to recognize you by their footsteps alone, and began to feel anticipation every time the door to his lab opened.
