- This group was the winner of the 2000 competition to see which of the shuffle units could sell the most copies of their single.
- After Danielle Delaunay graduated from Hello! Project and Shinoda Miho left due to T&C Bomber disbanding, their lines were given to Maeda Yuki and Yoshizawa Hitomi respectively in concert performances.
- Akai Nikkichou was later covered by two of the original Akagumi 4 members - Goto Maki on her album Makking GOLD 1 and Nakazawa Yuko on the album Together! -Tanpopo・Petit・Mini・Yuko-. Nakazawa's version has the English opening speech rewritten into Japanese, while the speech is absent from Goto's version entirely.
