The last of the "31" series will be the long-awaited 6th full album, released on November 11, the day the band was formed, about 1 year and 5 months after the last album "29". Next year will mark the 10th anniversary of Base Ball Bear's first major album "C". The title of the new album is "C2". This is the first episode of Base Ball Bear's second act and a new guitar rock milestone, which they have arrived at because they love guitar rock so much that they have hated it, experimented with it, and continued to examine it. The preceding "Extreme Single", "That's for Who? part.1", "Bunka Matsuri no Yoru", and "Mystery Night".
