All for One & One for All!

All for One & One for All! is the first (and only) mini album by Hello! Project unit H.P. All Stars, released on December 1, 2004 in both a normal and limited edition, the limited edition having a different cover. It reached a peak of #5 on the daily Oricon charts, lasting 7 weeks. The concept behind the song was to show the fans appreciation and celebrate Hello! Project's seventh anniversary, whilst sending a message of peace.

The title track features every member of Hello! Project at the time of release; however, the coupling tracks were sung only by a few specially selected singers. On the normal edition cover, the members are arranged in the shape of the letter "H" on the front cover, and the letter "P" on the back cover, representing the Hello! Project initials. The first pressing came with a 100-page photobook.
