The follow‑up single "Bīdama" followed on November 26, 2004, becoming the ending theme for Genshiken and including a cover of Magokoro Brothers’ Nagare Hoshi. In December 2004 she released her independent album Anata to Watashi to Kimi to Boku, and in April 2006 she issued her second independent album, Sora Iro Nostalgie. Her first major label album, Tokyo Cramzy Days, arrived on March 21, 2007, compiling tracks from earlier releases.
