The Head Teacher informs Mirai's family that Riko will be attending Mirai's school, also warning both Mirai and Riko not to let anyone know they can use magic. Along with her belongings, Riko also receives the crystal ball, Cathy, to keep in contact with the Magical Realm. The next day, as Riko joins Mirai's class under the name Riko Izayoi, both girls find themselves in a pinch as not only has one of their classmates, Kana Katsuki, spotted them riding brooms from afar, but Mofurun and Ha-chan have also snuck into school. Just as Mofurun comes across the Topaz Linkle Stone, she encounters Gamets, who summons a Cherry Blossom Plane Yokubal. Mofurun's desire to protect the school unlocks the Linkle Stone's power, allowing Mirai and Riko to transform into the Topaz Style and use its powers to defeat the Yokubal. Afterwards, Ha-chan, who was able to use defensive magic during the battle, grows into an older form and convinces Mirai and Riko to let her and Mofurun keep going to school with them.
