Amaryllis, Ginro and Kohaku are chosen to join the inner palace. The science team will need a way to communicate with them in secret, and, eventually, a way for them with the science team.
And tell them about the key of 
science that Kohaku-chan found.
.ونخبرهم عن مفتاح العلم الذي وجدته كوهاكو-تشان
Wir müssen ihnen vom Schlüssel
der Wissenschaft berichten.
Per dir loro che Kohaku 
ha trovato la chiave della scienza.
E contar para eles sobre a chave 
da ciência que a Kohaku encontrou!
Скажем им о ключе науки,
который ты отыскала.
