Round 3: NO LIMIT Part 1 (Episodes 7-8) (Kingdom: Legendary War)

The NO LIMIT round was divided into two parts - the first portion of the round would be a 3 vs 3 team effort, broken into Rap, Dance, and Vocal. The second part, the groups were given free reign - they could do anything they wished for their performance, invite any guest singer, etc.

For the first portion, Ateez (winner of the previous preliminary voting) was to choose the two groups that they wished to collaborate with. Via majority vote, they chose Stray Kids and BTOB. iKON, SF9, and The Boyz would be the second group. Each super group would choose a name for their team - Mayfly (BTOB, Stray Kids, Ateez) and It's One (iKON, SF9, The Boyz) - and would compete in 3 categories of Rap, Dance, and Vocal.
