Tomorrow X Together (TXT) has topped the Oricon Chart's Daily Digital Single Ranking with their Japanese single 5 'Setsuna Hanabi' released on the 17th. The title track immediately claimed the top position on Japan's iTunes Top Songs, while the music video secured the number one spot on LINE MUSIC's Music Video Top 100 for two consecutive days (17-18th) and also ranked first on YouTube's Music Video Trending Worldwide. 'Setsuna Hanabi' is a Brazilian funk track that metaphorically compares unavoidable separation to fireworks on a summer night, expressing bittersweet emotions about hoping the relationship continues despite knowing the end is approaching. The raw texture of the Brazilian funk genre, combined with the five members' delicate emotional expressions, maximizes the poignant sentiment. The music video features cinematic storytelling that encourages fans to deeply analyze and share interpretations. Additionally, TXT performed as headliners on the final day of 'KCON LA 2026' in Los Angeles (14-16th) with a nine-song setlist creating a concert-like atmosphere, while member Yeonjun opened the previous day's performance with a solo stage.
