In part #6 of their debut trailer film series 'The Absolute Beginning', all 5 members of AB6IX finally emerged through each of their white doorways and joined one another as a full group. 

Additionally, trailer film #6 revealed that each of the keys which appeared in the members' individual films - A, B, 6, I, and X - form the group's very own name. 

Stay tuned for more on AB6IX's unique universe, as their debut approaches this coming May.
