二階堂 藤乃

Protagonist's aunt. She was the protagonist's first love, and the woman who took his virginity when he was a child.

She considered Sayuri as her rival back when they were hostesses, as she was always second to her. After hearing news of Akihiko being abandoned by his wife, she rushed over to his house out of worry, and soon lived with him. Contrary to her sharp tongue and blunt personality, she's actually very kind and thoughtful.
