In the credits for Kingdom Hearts Unchained χ, found under settings we have noticed Success Corporation, the developers of Kingdom Hearts χ[chi] were one again contracted by Square Enix to co-develop Kingdom Hearts Unchained χ for iOS & Android. However, unlike Kingdom Hearts χ[chi] which was handled by Square Enix's Business Division 11, Square Enix's Business Division 3 were working on this title.

Business Division 3 is of course the Business Division where the Kingdom Hearts team is hard at work on Kingdom Hearts III. Square Enix also has two other titles in development in BD3 with the 25th anniversary title for SaGa and World of Final Fantasy. Don't be confused though, these are different teams. Shinji Hashimoto is the corporate executive of Business Division 3.
