Group History
Formation and Pre-Debut
EION was first introduced to the public in September 2025 under Wannabe Entertainment. The initial lineup consisted of five members: Heemin, Teo, Sihoon, Haru, and Hwiseong. However, the group’s composition quickly began to shift.
On September 22, 2025, it was revealed that Hwiseong was no longer part of the group, reducing the lineup to four members. Despite this change, the group pressed forward with their pre-debut plans.
October 30, 2025, marked a significant milestone as EION began their pre-debut Japan promotions as a four-member group. This strategic move into the Japanese market demonstrated Wannabe Entertainment’s ambition to establish EION as a group with international appeal from the very beginning.
Lineup Changes and New Members
The group’s journey has been characterized by several lineup adjustments. On December 19, 2025, Heemin departed from the group. Heemin later explained that he left after realizing it was not a positive atmosphere for him to continue creating music.
In early 2026, EION added new members to strengthen their lineup. Minjae and Hyun joined the group, bringing the total to four members. Hyun, in particular, was introduced as the new maknae (youngest member) of the group.
Teo, who had been part of the initial lineup, also departed from EION at some point between January and March 2026. With these changes, the final pre-debut lineup was solidified as Sihoon, Haru, Minjae, and Hyun.
Pre-Debut Activities and Japan Promotions

The group returned for a second season of performances from January 17 to February 24, 2026, under the title EION ~2026 EION LIVE IN JAPAN~Neverland~.
These performances have allowed fans to experience EION’s music and stage presence firsthand.

Special member-themed days were held throughout the season, including TEO DAY (January 29), MINJAE DAY (February 5), HARU DAY (February 13), and SIHOON DAY (February 19).
Following these successful promotions, EION announced another series of performances, EION ~EYES ON YOU IN TOKYO~, which began in February 2026 with the new maknae Hyun joining the lineup.
Official Debut

The group has reportedly been holding auditions to select additional members, with some sources suggesting the final group may consist of six members. However, as of the latest available information, EION continues to promote as a four-member group.
Agency and Management
EION is managed by Wannabe Entertainment. The agency has been actively promoting the group through pre-debut activities, particularly in the Japanese market. Wannabe Entertainment has also been holding auditions for additional members to join EION.
