LE SSERAFIM (Hangul: 르세라핌) is a 5-member South Korean girl group formed and managed by both Source Music and HYBE. They debuted on May 2, 2022, with their first mini album titled FEARLESS, supported by the title track of the same name. Originally consisting of six members, Kim Garam left the group on July 20 of the same year after her contract had been officially terminated.

The group’s name itself is an anagram for the group’s motto, which is “I’M FEARLESS”, and it implies the group’s confidence and strong will to fearlessly move forward without being swayed by the world’s gaze. Furthermore, LE SSERAFIM—while being a 5-piece group—is derived from Seraph, a 6-winged heavenly being which is mentioned as the highest-ranking angel in Christian angelology.

On March 14, 2022, both companies announced the launch of their new girl group, and a confirmation that the former members of IZ*ONE, Miyawaki Sakura and Kim Chaewon were to be the part of its lineup. Later on, the individual video teasers were uploaded onto HYBE’s official YouTube channel in mid-April of the same year, unveiling their other new members: Hong Eunchae, Kazuha and Huh Yunjin, who is known for representing Pledis Entertainment on the 2018 Mnet survival show Produce 48, in which Chaewon and Sakura participated as well. Soon after, it was revealed that LE SSERAFIM’s first extended play will see its daylight in early May. Additionally, on August 8, the group announced their fandom name, FEARNOT, which is a homonym of “blooming” (피어나) in Korean.

On September 1, Source Music revealed to Newsen that LE SSERAFIM is preparing for their first comeback, which was rumored to be out later that year. The group’s second mini-album, ANTIFRAGILE was released on October 17, 2022, with its roll-out began with an upload of its official trailer named “The Hydra” on September 26.

On January 25, 2023, LE SSERAFIM officially make their Japanese debut with the single FEARLESS, which was announced on the group’s social media sites two months prior.
