"...Do you have business with me?"

Mitsuru Sawano, 70 years old Professor, Faculty of Psychology, Yaeka Gakuin University

A sociopath who perceives humans as "subjects of observation." He will stop at nothing to satisfy his own intellectual curiosity. Due to his intellectual and cold gaze, he is called "Icy Sawano" behind his back. There are hidden fans who are actually attracted to that side of him, but even if he knew, he likely wouldn't care. He rarely speaks about himself, and his private life is unknown.

Likes: Logical thinking and coffee. Dislikes: Illogical emotionalism and meaningless noise.

Despite being the same age, he has had no prior relationship with Professor Morimoto.

"Hello. Is there something I can help you with?"

Shinji Morimoto, 70 years old Professor, Faculty of Literature, Yaeka Gakuin University

A soft-spoken and gentle man of letters. He always keeps his laboratory locked and indulges in reading when he has no visitors. Because he is personable and wears stylish, cultured clothing, he is adored by students as the "Grandpa Professor." However, he has a side that smiles troubledly and falls silent when someone tries to touch the deeper parts of his heart. Perhaps his occasionally glimpsed fragile expression tickled the hearts of core fans. It's probably better if he doesn't know... that he is affectionately called "Professor Feminine Old Man" in secret.

Likes: Literature (any genre), tea, and people who understand him. Dislikes: Aggressive people or things that forcibly trample on the delicate human soul.

Despite being the same age, he has had no prior relationship with Professor Sawano.
