Teranishi Takuto, Hara Yoshitaka, and Imae Daichi have joined the new member auditions for Timelesz.

In April, the group announced their rebranding from Sexy Zone to Timelesz and unveiled plans for a new member audition. Since September 13, the Netflix series Timelesz Project -Audition- has been following the audition process. From 18,922 applicants, the first round narrowed the field to 350, the second to 36, and as of episode 06, released on November 29, the top 15 candidates were revealed.

Teranishi, who joined STARTO Entertainment in 2008, Hara in 2010, and Imae in 2009, are currently active as actors. The three will join the audition as candidates during the fourth round, held over three days at a facility in the Kanto region. Due to scheduling conflicts, Hara will begin participating on the second day.

The fourth round's challenge involves performing three songs from Timelesz’s repertoire from their Sexy Zone era: Jinsei Yuugi, Right Next to You, and Purple Rain.
