Miracle Plan ga Dekichatta! (ミラクル・プランができちゃった！)

"Miracle Plan ga Dekichatta! (ミラクル・プランができちゃった！)" is the opening theme of the 2009 anime Akikan! (アキカン!). Performed by the Japanese idol unit Charmmy Queen, the song introduces Brain's Base's television adaptation with a bright J-Pop sound that matches the series' comic premise. It was released in 2009, the same year as the anime.

The track moves at a brisk pop pace and leans on buoyant, tightly coordinated vocals. Its structure favors a quick, memorable chorus and a glossy idol-pop finish rather than dramatic weight. The melody stays light on its feet, giving the opening an energetic, mischievous tone.

That approach fits Akikan!'s absurd romantic-comedy setup, where ordinary school life collides with girls who transform from drink cans. The song's upbeat momentum frames the series as playful chaos from the start. Public reference material on Charmmy Queen identifies the performers as a Japanese female idol unit, a background that aligns closely with the song's polished pop presentation.
