None of the three other titles are major titles, often remaining inactive for months or even years. She also works for Wave's sister promotion Osaka Joshi Pro Wrestling as Shitennouji Moeko . "Moeka Haruhi" is not her real name, but rather a stage name highlighting her cutesy, cosplaying persona.

Pro Wrestling Wave , is a women's professional wrestling, or Joshi Puroresu, promotion created in 2007 after the dissolution and closure of JDStar. The company was formed by Mikiko Futagami, or Gami, former JDStar wrestler Yumi Ohka, and former JDStar booker Tatsuya Takeshi, who assumed the role of President for the new company. The company has had a very slow growth and grassroots rise, and is one of the few women's promotions in Japan to do shows on weekdays.
