Rookie boy group Just B has unveiled a shadowy new set of individual concept photos for 'Just Beat'.

In this set of images, the Just B members give off a mysterious mood as they explore with the theme of 'Light and Shadow'. On some of the members, light effects depicting letters and numbers such as "1252" and "διακρίνω" add to the air of secrecy, as the team prepares to return with a more mature, upgraded image and sound.

Meanwhile, Just B debuted as a 6-member group under Blue Dot Entertainment back in June of this year. This will mark the group's first comeback since debut. 

Look out for Just B's 'Just Beat', out on October 27 at 6 PM KST!
