Koihime Musou Temporada 2 Episódio 4

The Chou sisters try to get their money by performing magic and music, though its hard to deal. A man claiming himself Ukitsu gets them a little dream and gives them the Taihei Youjutsu (Crucial Keys to the Way of Peace) book full with magic references. Chouhou uses the magic to create three magic crystals (somehow it resembles a microphone) and the three sisters plan to put their first magnificent performance using this, and they get successfully. Their successes come one by one, and they have been famous more and more ever.
