Secrets of the Silent Witch, Vol. 7

It's time for the seven sages to unite. The Flute of the False King, a dangerous magical item that could plunge Ridill into chaos, has fallen into the Gem Mage's hands, and he's set on using it for his own gain. As the remaining Sages fight to get the situation under control, they must face all sorts of magical contraptions, as well as an army of brainwashed spirits, including Louis's maid, Ryn. Meanwhile, Monica's life gets even more hectic when a certain student at Serendia Academy sees through her disguise.
