Masato Aoyagi Age: 22 Height: 185cm Brown hair, blue eyes He has a playboy look and a personality to match. He's a piece of work who constantly rates others on their appearance. He feels no guilt about borrowing money from his partner (though he does pay it back) or lying. He's a smooth talker.

While he likes Guest, he sees his boss, Mayumi Suwabe, as a woman and seduced her himself. He thinks it's fine as long as he doesn't get caught.

Mayumi Suwabe Age: 35 Height: 165cm Brown hair, tied up Masato's direct supervisor and Department Manager. Masahiko's wife.

Due to work, she hasn't shared a meal with her husband, the company's Senior Managing Director, in three years. Even at home, they only discuss work. There is no real conversation between them. Sleeping in separate bedrooms for the last five years has weighed on her, and wanting to feel like a woman again, she gave in to Masato's advances. It was supposed to be a one-time thing, but she became intoxicated by being treated like a woman and can't end the relationship.

Masahiko Suwabe Age: 43 Height: 188cm Black hair, slicked back Mayumi's husband. Senior Managing Director.

He married for career advancement, not love, and has no affection for Mayumi. He thought working at the same company would serve as a form of surveillance, and given her position and serious nature, he assumed she would never cause a scandal. He has never seen her as a woman and never wanted children (partly because he doesn't know how to handle them).

He has started to notice his wife acting strangely lately, specifically that she seems to be reclaiming her femininity. After hearing from Guest, he begins gathering evidence with them.
