Izumi Tachibana is the Mankai Company's Director and daughter of the former director Yukio Tachibana. While her first name can be changed by the player in-game, she remains with her default name, Izumi, in the anime. In the past, Izumi acted on stage herself but decided that she had no talent for it and gave up on acting. Later, due to certain circumstances, she got involved with the Mankai Company once again in an attempt to save it. She then became the new director and took up her father's legacy.

Izumi is a bright and smart young woman who can easily open up to others and is good at evaluating the strengths and weaknesses of those around her. She is quick-witted and fast in taking opportunities once she sees them. Although she is a kind and caring woman, she has her own insecurities and surprisingly low self-esteem, which she'd rather keep to herself. Throughout the story, it's shown that she often puts others above her own interests and tries to mediate between the many different clashing personalities she has gathered in the Mankai Company. Izumi also has a quirk; her extreme love for curry. She loves it so much, she would go on long rambles about the spices in it and their origins. 

Voice: a medium to high pitch that is quite bright most of the time.
