TO1 have kicked off a series of charismatic comeback teaser posters for their 2nd mini album, 'RE:ALIZE'. 

The first TO1 members up in a set of 'Real X' version individual posters are Jerome, Kyungho, Jisu, Chan, and Donggeon. The boys exude an upgraded, calm and quiet charisma, as they prepare to return with a more mature image after their "Son of Beast" promotions earlier this year. 

Meanwhile, TO1 will be unveiling three unique sets of concept teasers leading up to their full comeback, including the 'Real X' version, the 'Lie X' version, and the 'MIX' version. The group's 2nd mini album 'RE:ALIZE' is slated for release on November 4 at 6 PM KST.
