Luminous, a South Korean boy band formed and managed by SE Group Entertainment (formerly Barunson WIP), debuted on September 9, 2021. The group consisted of four members: Youngbin, Suil, Steven, and Woobin. The band's concept revolved around a fictional universe where each member symbolized different elements.

Their debut EP Youth was released following the pre-debut EP Vision, which included the lead single "Dreaming Luminous". Their second EP, Between Light and Darkness (Self n Ego), was released on January 20, 2022, followed by the single "Wish You Were Here" in May of the same year. The group's first studio album, Luminous in Wonderland, was released on August 17, 2022. Luminous disbanded on February 9, 2025.
