In February 2007, Suzuki officially started a new project called "join", in which she would be collaborating with different artists and experimenting with various music styles. The collaboration singles with Buffalo Daughter, THC!! and Kirinji were released in a three-week period starting on 28 February to 14 March. Her "join" album and second Avex album, "Connetta", was released on 21 March, and included collaborations with several artists including Hideki Kaji, Scoobie Do, Ayano Tsuji and Northern Bright. The album peaked at number twenty-six on the Japanese Oricon charts. Her acting career went more seriously at this time; she starred in the live action drama "Skull Man", and also recorded the Japanese-South Korean collaboration drama "Under the Magnolia", in which she starred the leading role along with Lee Wan and travelled to New York and South Korea to shoot certain scenes. She was also invited for a third time at 2007's a-nation, where she was chosen as the opening act.
