is a song by Japanese musician Ringo Sheena, which acted as one of the promotional songs from her fourth album Sanmon Gossip in 2009. The song was produced by Sheena's former Tokyo Jihen bandmate Masayuki Hiizumi, and was a collaboration with Hiizumi's jazz ensemble Pe'z, as well as hip-hop group Maboroshi members Daisuke "Mummy-D" Sakama and Tomoyasu Takeuchi. Background and development In 2007, Sheena resumed releasing music under her solo name, after working as a member of Tokyo Jihen since 2004. She released the soundtrack album Heisei Fūzoku in February, a project where she collaborated with composer Neko Saito to create music for the Mika Ninagawa-directed film Sakuran. In September of the same year, Tokyo Jihen released their third album, Variety, a project album featuring members other than vocalist Sheena composing the album's music. After their 2007 Spa & Treatment tour, this began a two-year period of inactivity for the band. In November 2008 to celebrate her 10th as a solo musician, Sheena held a series of three concerts at the Saitama Super Arena, Sheena Ringo (Nama) Ringo-han '80: Jūshūnen kin'en-sai.

On May 27, Sheena released a single called "Ariamaru Tomi", which was used as the drama Smile'''s theme song.
