AmbiO
AmbiO (엠비오) is a five-member multinational boy group under E Entertainment that officially debuted on March 18, 2026 with their first mini-album Boys Be Ambitious. The group consists of Tetsu (Taiwanese leader/rapper), Jeesoo (Korean-Canadian rapper), Ruone (Japanese vocalist/dancer), Kiwon (Korean vocalist/dancer), and Seungsang (Korean vocalist/dancer, youngest) -- four nationalities across five members.
Their name is a direct abbreviation of "Boys Be Ambitious," a philosophy that runs through everything the group does. Before their Korean debut, AmbiO spent months building live performance experience in Japan, releasing three pre-debut singles -- "Runnin'" (September 2025), "I Wish" (October 2025), and "Click" (November 2025) -- and accumulating stage hours that most rookie groups do not have on debut day. Member Kiwon pushed further, releasing the Japanese-language solo ballad "Kokoro" in December 2025, three months before the group went official.
The debut title track "SHOWTIME" pulled over 200,000 YouTube views within the first 24 hours. Built on dynamic guitar riffs and rhythmic call-and-response hooks, it is designed for arenas. Two members with survival show credentials -- Ruone (MAKEMATE1) and Kiwon (BOYS II PLANET) -- and a frontman who trained for years before any camera ever pointed at him. This is not a group making it up as they go.
