ZEROBASEONE will reveal the stage for their new song "Customize" for the first time before their comeback. On the 5th, ZEROBASEONE, consisting of Seong Hanbin, Kim Jiwoong, Seok Matthew, Kim Taerae, and Park Geonwook, announced that they will perform the "Customize" stage for the first time at the "KCON JAPAN 2026" event held at Makuhari Messe in Chiba Prefecture, Japan, on the 10th.

"Customize" is a track included in ZEROBASEONE's sixth mini-album "Ascend-", scheduled to be released on the 18th. This song is an original composition with lyrics and music written for the first time by member Park Geonwook. Based on the pop rock genre, it expresses the ironic state of losing oneself the more one immerses in emotions.

Park Geonwook said during a live broadcast on the afternoon of the 4th, "From the beginning, I wrote the song thinking it would be cool if all five of us sang it. It's a song only ZEROBASEONE can do." He added, "I directed the recording session, and the hyungs all did really well. I'm curious about the reaction when it's released, so I want to share it with you soon. We will meet shortly."

The sixth mini-album "Ascend-" includes a total of seven tracks: the title track "TOP 5," "Customize," "Intro.," "V for Vision," "Exotic," "Changes," and "Zero to Hundred." The new album will be released at 6 p.m. on the 18th through various online music platforms.
