The six-member girl group LIGHTSUM is attracting attention with a new challenge of being reborn as a “Japanese-style idol.” From their major debut mini album “Re:idol,” scheduled for release on September 23, distribution of the lead track “Doshite” started today (the 16th). “Doshite” is a number full of pop and cute charm, depicting a bittersweet unrequited love in which one is happy or sad depending on the words and actions of the person they like. It has become a song packed with “kawaii” that is fitting for LIGHTSUM, who have been reborn as Japanese-style idols. In the MV teaser released at noon today, it begins with cuts of Hina, whose loveliness stands out, and the members wearing new visuals appear one after another in different spaces. It is finished as a video that raises expectations for the story development from each of their expressions. In addition, on September 23 (Wednesday) from 8:00 p.m., LIGHTSUM will hold their first YouTube live broadcast on the official LIGHTSUM YouTube channel, where the members will appear in real time and enjoy interaction with fans through chat. Furthermore, from 9:00 p.m. after the live broadcast, the full MV of “Doshite” is scheduled to be premiered on YouTube. Starting with the final episode broadcast of the ABEMA documentary “Re:Idol” on September 20 (Sunday), they are also scheduled to appear at “SBI MUSIC CIRCUS HOKKAIDO” on the 26th (Saturday). From the 27th (Sunday), release events touring Hokkaido, Tokyo, and Osaka have also been decided for LIGHTSUM. Attention is gathering on their future activities as they fully begin operations in Japan. ■Release information Pre-release single “Doshite” Released September 16, 2026 Streaming and download here ■Related link LIGHTSUM official website ■Release information Pre-release single “Doshite” Released September 16, 2026 Streaming and download here ■Related link LIGHTSUM official website
