the concert tour "Under Babies". On July 27, 2018, Onitsuka announced that she had been married since 2015. "Hinagiku", the lead single from Onitsuka's ninth studio album, was released in August 2018. In December 2018, Onitsuka performed two concerts entitled Beekeeper, in Osaka and Tokyo. Artistry In 2002, music critic Tetsu Misaki noted that Onitsuka was one of the few pop singers to sing about anger, citing lyrics such as in "Shine" (2000) and in "Gekkō" (2000). He praised her "strong spirit" and writing without hesitation, but felt like her lyrics were not like standard poetry, as they dealt with unpolished things. Misaki also noted that her lyrics were difficult to interpret, despite the fact that she does not use complicated words. He contrasted her lyrics to that of Ayumi Hamasaki who, in the early 2000s, wrote about an "easy to understand sadness," whereas it was not so clear what caused the sadness in Onitsuka's lyrics. Misaki further noted Onitsuka's use of body parts in her lyrics, especially legs, which is not common in Japanese popular music. Misaki noted that Onitsuka's song titles had little to do with their lyrical content causing discord. He pointed out "Gekkō" as being moonless, "Memai" not to do with dizziness and "Rasen" which, instead of having a spiral theme to the lyrics, seemed to talk about moving forward. However, "Memai" can be interpreted as a psychological dizziness because of the instability of the narrator and her need to be emotionally sheltered. "Rasen" can be interpreted either as the end of a chapter in her life, which is often called a spiral, and the beginning of a new and better one; or as a suicide song, and the spiral of emotions that lead there, such as anger, doubt, not being able to forget a loved one. Domestic violence On August 18, 2010, Onitsuka was assaulted by her boyfriend Yusuke Komiya in her apartment. Onitsuka and Komiya had been dating since September 2009 and the two shared an apartment together. Late at night on August 18, Komiya was out drinking and came home completely drunk. While Onitsuka was sleeping, Komiya punched her in the eyes. Onitsuka then tried to retaliate but was severely beaten resulting in several broken ribs. Onitsuka began her lawsuit against him on December 16, 2010. Discography Insomnia (2001) This Armor (2002) Sugar High (2002) Las Vegas (2007) Dorothy (2009) Ken to Kaede
