Kira Kira and Healin' are available in North America, Latin America, Australia, New Zealand, South Africa, Europe, and MENA. Not sure which markets Futari is available in. This morning it was saying "not available", this evening it was, despite having a VPN set to the same country both times (although different servers).
Max Heart, Fresh and Yes Precure 5 are also in the CR database, but are listed as "for informational purposes".
