There are several artists with that name. 1. Rey is a Japanese band who signed onto the Lantis label in 2008. They are described as the "real anison band" (本気のアニソンバンド honki no anison bando?) for their performances of anime theme songs. Front man Kenta Harada claims that their band's name comes from both Hironobu Kageyama's band Lazy and the anime character Rei Ayanami. The group's debut single under Lantis was used as the first ending theme of Tomica Hero: Rescue Fire.
