Cassette Girl is a girl with long black hair, wearing a purple hoodie, who always listens to music while carrying her small player. Cassette loves cigarette smoke and won’t part with her smoking cigar for a second. When Boyfriend meets the music and tobacco lover, a rhythm battle is unleashed between the two, as they both consider themselves consummately talented vocalists.
The rhythm battle against Cassette Girl will take place to the following songs on One Dark Street: “Ukiyo”, “Earworn”, “Machine”, “Soda Groove” and “City Funk”. Help the guy not to fall in the eyes of his girlfriend and defeat Cassette Girl in all stages of the competition. There are two modes in the game: in the story you can’t choose a song, and they will change alternately, but in the free game, the songs are available to your choice. In either case, you have to play the tunes to the end to win. If you don’t miss often, but make the key clicks on time, Beaufrand will be the winner.
