An American who grew up in Hakata since she was 5, Tina Foster was at first the shy girl who loved photography since she was in elementary school. After she met Kaoru Hanabishi and fell in love with him, she always tries to have a good time and have good memories with everyone. Tina also has this fascination with boobs. She tends to have the habit of grabbing everyone's boobs (especially Taeko's) and can tell how big they are, or even if they have gained weight. Always positive on the surface, Tina still can't hide her true love for Kaoru, even though she knows of his relationship with Aoi.
