Tsuma Shibori

The game opens in the month of December. The main character, Shinba Kousuke is a 4th year college student, 3 months away from graduating (Japanese academic years break off between March/April), and recently has a job lined up. Kousuke has never had a girl friend, and his father arranged a special omiai for him. Kousuke is forced to live under the same roof with his omiai partner, Kodotsuki Madoka. Madoka's older sister, Aoi Sakura (married), also lives with the two young adults to keep an eye on the progress of the omiai.
