Overview
にめんせい☆ウラオモテライフ！ (Nimensei☆Uraomote Life!) is the opening theme of the anime series Himouto! Umaru-chan R (干物妹！うまるちゃんR), the second season of the franchise starring Umaru Doma. The title translates to "Two-Faced☆Front-and-Back Life!", a direct reflection of the show's central conceit: Umaru projects the image of a flawless, studious high school girl in public while retreating into a cocoon of video games, cola, potato chips, and utter laziness the moment she steps through her front door.
Composed, arranged, and written by the prolific rhythm-game composer duo Massive New Krew (Ayato Shinozaki and Ryosuke Tachibana), the track charges forward at a brisk 170 BPM with an upbeat pop-rock energy befitting an anime opener. The lyrics are littered with in-universe references: Umaru's secret alter ego UMR, her catchphrase "WARNING WARNING," and her demanding attitude toward her long-suffering older brother. The vocals are performed by Aimi Tanaka, Umaru's voice actress, performing in character.
In maimai, the song arrived with the MiLK PLUS update on July 24, 2018, both the standard charts and the Re:Master chart launched the same day. Licensing restrictions complicated its regional availability: Asian-region cabinets did not receive the song at all until the first maimai DX release for Asia, and it was pulled from those cabinets starting with maimai DX Splash. Globally, the song was delisted from all versions on March 18, 2021, making it a legacy track no longer accessible on current cabinets.
The chart set spans five difficulties with three credited notes designers. The Expert chart (level 9) was designed by サファ太 (Safata), the Master chart (level 10+, constant 10.6) by 緑風 犬三郎 (Midorikaze Inusaburō), and the Re:Master chart (level 11+, constant 11.6) by LabiLabi.

- The title plays on two Japanese words: にめんせい (nimensei, 'two-faced' or 'dual-natured') and ウラオモテ (uraomote, 'front-and-back' or 'public-and-private'), both describing Umaru's split personality between school and home.
- The song was composed and arranged by Massive New Krew (篠崎あやと and 立花亮佑), a duo well known in the rhythm game scene for contributions to BEMANI, SOUND VOLTEX, and multiple earlier maimai tracks.
- The lyrics include Umaru's signature catchphrases and references to her secret identity UMR, her demands for cola and potato chips, and her reliance on her older brother.
