Hello!! Kiniro Mosaic

Although learning different languages continues to be an interest for Shinobu and her friends, the new school year brings unexpected difficulties. Not only is there always something new and different to distract them from their studies, but Alice and Yoko also are having trouble adjusting to being in a different class from Shinobu and Aya. Meanwhile, Karen isn't getting along at all with her new homeroom teacher, and it doesn't help that the teacher is having trouble figuring out how to make herself seem friendlier to her students as well. Craziness may ensue, but sometimes, all it takes is the right mutual experience to bring everyone together.
