Each limited edition has a different member on the cover. The single debuted at the 1st place in the Oricon Daily singles Chart and at the 3rd place in the Oricon Weekly Singles Chart, selling in that first week 22,537 copies.

On September 26, 2012, Momoiro Clover's already former label Universal J re-released the single under the title of {{nihongo|"Ikuze! Kaitō Shōjo (Special Edition)"|行くぜっ！怪盗少女 ～Special Edition～}}. The 2012 re-release was a repackage of the original version. It only had one version, with the cover of the original Regular Edition, but it included a DVD with the original music video for the song "Ikuze! Kaitō Shōjo".{{cite web|url=http://tower.jp/article/news/2012/08/15/n06|title=ももクロ"行くぜっ! 怪盗少女"PVが初DVD化! スペシャル版シングル登場|publisher=Tower Record Online|date=2012-08-15|access-date=2012-12-13|language=ja}} The re-release debuted at number 6 in the Oricon daily singles chart and at number 7 for the week.

In some scenes of the music video, the members appear wearing costumes of a maid, a nurse, a policewoman, etc. The dance routine for the song incorporates intense acrobatics.{{cite web|url=http://tv.bunka.co.jp/top/topix/2011/0425/momoclo-3d/index.html|title=ももいろクローバーZ、三菱3Dディスプレイのタイアップ決定！｜アイドル誕生！ＴＶ|publisher=Bunkasha|access-date=2012-12-13|language=ja|url-status=dead|archive-url=https://web.archive.org/web/20130306050607/http://tv.bunka.co.jp/top/topix/2011/0425/momoclo-3d/index.html|archive-date=2013-03-06}} One of the highlights of the video is Kanako Momota performing a so-called {{nihongo|"shrimp jump"|えびぞり}} (an upward jump with an arched back and both legs bent backwards, called a sheep jump in gymnastics). The jump is also the highlight of the group's live concerts.{{cite web|url=http://natalie.mu/music/news/54018|script-title=ja:ももクロ東京タワーで「オレンジノート」アカペラ大合唱|publisher=Natalie|date=2011-07-31|access-date=2012-12-13|language=ja}}{{cite web|url=http://natalie.mu/music/gallery/show/news_id/58889/image_id/98804|title=ファッションショー！お悩み解決！ももクロ女祭り大成功|publisher=Natalie|date=2012-12-13}} Also, at live performances of the song Shiori Tamai and Momoka Ariyasu do cartwheels and Kanako Momota performs a handspring.

On March 3, 2010, Momoiro Clover held a public signing ceremony for a contract to debut on a major label. It had already been determined that their future single would be "Ikuze! Kaitō Shōjo" and that it would be released on May 5. But, in order for the contract to be signed, the members had to pass a weight test. Each contractee was not to exceed an index determined by the formula: {{math|Idol weight (kg) {{=}} [Height (cm) − 100] × 0.8}}. If they did not pass, only a temporary contract would be signed. In the presence of around 200 fans and reporters, everyone had an "idol" weight except Reni Takagi who exceeded the limit by 0.8 kg. Therefore, it remained unclear whether the group would succeed in passing the test by May 5. At the same ceremony, the girls stated their goals for the year ahead, setting them as "To take the first place on Oricon, participate in Kōhaku Uta Gassen, give a concert at Budokan, and in Budokan to hold a handshake meeting with all the fans who came".{{cite news|url=http://www.oricon.co.jp/news/confidence/73976/full/|date=2010-03-04|access-date=2012-12-13|publisher=Oricon|language=ja|script-title=ja:ももクロ、公開体重測定でアイドルメジャーデビューが"仮契約"に}}

From March 6, Momoiro Clover started a tour in support of the single. They were to give 28 concerts.

On May 3, 2010, the single debuted at the top of the daily Oricon singles chart. On May 4 it fell to the 14th place and on May 5 rose to number 12.{{cite web|url=http://jp.news.gree.net/news/entry/525157|script-title=ja:予約握手のコバンザメ商法!? ももクロ、デイリー1位も翌日14位に急落|author=Cyzo|publisher=Gree|date=2012-05-08|access-date=2012-12-13|language=ja|url-status=dead|archive-url=https://web.archive.org/web/20130119062946/http://jp.news.gree.net/news/entry/525157|archive-date=2013-01-19}} In the Oricon weekly singles chart, it debuted at the 3rd place with 22,537 copies sold.
