ONE OR EIGHT will perform "Yellow Brick Road," the ending theme for the second season of anime Black Clover. The new season will premiere on October 3, with the song set for digital release on October 7.

"Yellow Brick Road" was created around the similarities between ONE OR EIGHT's own journey and the story of Black Clover, which follows Asta as he continues pursuing his dream of becoming the Wizard King despite the challenges he faces.

Member MIZUKI, who has followed the manga since it began serialization, commented, "'Yellow Brick Road' reflects the parallels between Asta and his friends, who face challenges together and continue moving forward beyond their limits, and us at ONE OR EIGHT, as we take on the world from Japan together with all of our 1DERZ."

ONE OR EIGHT debuted in August 2024 and has since expanded their activities internationally. The group will hold their ONE OR EIGHT Special SHOWCASE 2026 in ASIA -V8- in Singapore, Bangkok, and Manila this October.

They are also scheduled to embark on 'ONE OR EIGHT SHŪKAI 2026-2027 in JAPAN -2GATHER-,' a fan meeting tour visiting all 47 prefectures of Japan.
