By-Sexual (stylized as BY-SEXUAL) was a Japanese visual kei punk rock band from Osaka. They were active from 1988 to 1995, when vocalist Sho left the band and they went on hiatus. In August 1996, the remaining members restarted the group under the name By-Sex (stylized as BY-SEX) with Ryo taking over vocals in addition to guitar. In February 1998, Nao left and the group disbanded.
On September 3, 2011, By-Sexual reunited for a show at Shinagawa Stellar for the victims of the 2011 Tōhoku earthquake and tsunami. Around the same time, Ryo and bassist Den teamed up with their Zigzo bandmate Sakura to perform as By-Sex. The four reunited again for the October 14, 2016 Visual Japan Summit at Makuhari Messe and Chain the Rock Festival on August 26, 2017.
