Hana Shiraboshi, a high school student whose mother is the CEO of the White Star Talent Agency, is assigned to produce an idol group for the agency's 10th anniversary. Hana's nosebleed occurs whenever her she sees potential in others, and she uses it to scout five boys: Kiri Kurose, Rei Shinozuka, Junpei Akamatsu, Kazuhiko Midorikawa, and Yugo Aoyagi. Together, the five debut as the boy band Crash, with Hana as their manager. To reach their goal of becoming the top idol group, with the help of Hana, Crash gains experience through singing, acting, and dancing.
Two years later, Crash has become a successful group. Yui Sakura, Kazuhiko's childhood friend, becomes Hana's assistant in managing the group at White Star on his recommendation. As Yui helps Crash with their entertainment activities, she falls in love with Rei. Meanwhile, Kazuhiko reveals to Yui that he has been in love with her since childhood.
Crash! is written and illustrated by Yuka Fujiwara. It was serialized in the monthly magazine Ribon from the May 2007 issue to the December 2009 issue. Fujiwara created the series due to the growing popularity of idols in media, and she had based all members of Crash on characters from her previous works. As the original story arc of Crash! was concluding, Fujiwara was asked to continue the story with a new main character as the focus. After consideration, Fujiwara published a second act in Ribon from the April 2010 issue to August 2013 released on July 3, 2013. The second act, published as Act 2: Brand New Happy Wave in the bound volumes beginning with volume 8, introduced Yui Sakura as the new main character. The chapters were later released in 16 bound volumes by Shueisha under the Ribon Mascot Comics imprint. During the series' run, a vomic was released on Shueisha's website in 2009, which adapted the first chapter. A media mix project was announced on October 2, 2010 through the November 2010 issue of Ribon, consisting of a second vomic billed as a special version and a song produced exclusively for the series. The special edition vomic released in 2011 with a new voice cast and original story. It was also later released as a magazine gift on DVD with the June 2012 issue of Ribon on May 1, 2012. The song was announced on November 2, 2010 through the December 2010 issue. Titled "Crash on You", the song was produced by Elements Garden with lyrics by Fujiwara, featuring the new voice cast. The lyrics to the full version of the song were available as an online preorder bonus of volume 10 of the manga.
