To commemorate the 25th anniversary of Base Ball Bear's formation and the 20th anniversary of their major debut, all five CDs released in 2006 are being released on analog format for the first time! This work is their first major single, released on June 21, 2006, and includes the energetic title track that heats up the stage at summer festivals, as well as two songs not included on the album "C," including a newly recorded version of a popular song from their indie period. It comes with a special 7-inch E-style sleeve + an eight-page insert reproducing the design of the original CD.
