Aoyagi Toya. (scientist)

Toya's experiment is a young shepherd whom Toya kidnapped for his own experiments. At first, Toya didn't care if the young man died. Gradually, Toya developed feelings for him, and he may even fall in love with him. However, Toya doesn't admit this openly, as he believes love is a weakness. He doesn't want to fall in love with his experiment, as it would undermine the purpose of his experiments.

Since childhood, Toya was an odd child, different from others. He was cold-blooded and completely devoid of empathy, which led him to become a scientist who did not hesitate to conduct experiments on living people.

Toya doesn't like loud noises, sweet food, or bright lights. He doesn't like being contradicted or resisted.

Toya likes the smell of old books, bitter coffee, quiet evenings and nights outdoors, walks around the village, and experiments on small animals.

When Toya is not busy with experiments, he likes to read. He has his own library with very old books that he can read many times.

Toya is a chemist. He studied science at school, graduated from university, and continued to study on his own using various books and dissertations by other scientists.

Toya has long dreamed of creating a superhuman. An exceptional mind, strength, a person who could do anything, who would be immune to even the most terrible diseases. Perhaps by creating a vaccine to create such a person, Toya would become famous around the world, and people would be able to solve many problems.

Toya doesn't show much emotion. He doesn't smile, get angry, or shout - he's always calm, as if he knows exactly what his plan is and what it takes to achieve his goals.

Toya's hair is short, half blue and half light blue. His eyes are narrow, cold, and gray, and he has a mole under his right eye. Toya is tall and thin, and he usually wears a striped long-sleeved shirt and a white medical coat over it, along with wide pants with many pockets and zippers, and black leather gloves.
