Established at the 2013 corporate restructure of Square Enix, Business Division 6 would primarily handle development for mainline Dragon Quest games, including Dragon Quest Monsters and Dragon Quest Heroes. Along with this, they would also supervise the development of future Nier games including widely acclaimed Nier: Automata, and the newly introduced Bravely Default.

At the closing of 2019 this division would be merged to Creative Business Unit II.
