The Spike Chunsoft website listing for the Robotics;Notes Double Pack has been updated to clarify that, like Robotics;Notes Elite, Robotics;Notes DaSH will be rated “Teen” (ages 13 and up) in North America.
It’s worth noting that the ESRB has yet to officially list the game on their website, and other listings for the game (such as its official website and its North American pre-order listings) have not yet been updated to reflect the change. It may be worth taking this information with a small grain of salt until the ESRB officially lists the game on their website.
