ATEEZ's 2nd Japanese single album 'Limitless' was released on March 22 KST. 

'Limitless' captures the image of those who constantly overcome the battle against themselves and level up. The album contains the title song "Limitless" and "DIAMOND".

The title song "Limitless" contains the message of "don't give in to any adversity and believe in your potential and run", while the b-side song "Diamond" has a message of "like a perfect diamond, we all continue to shine toward our dreams". With these themes, both songs convey hope and positive energy.

In the music video for “Limitless,” ATEEZ drew attention by showing new visuals, such as training themselves through various sports. To parallel the message of the song itself, they are shown growing up one step at a time, creating catharsis.
