Koihime Musou Season 2 Episode 4

The Three Chou Sisters Acquire the 'Crucial Keys to the Way of Peace'

The Chou sisters try to get their money by performing magic and music, though it's 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. In the way to Enjutsu's city, Ryuubi is caught off by a poster of the Chou sisters, she suggests the party to take a look at them. The party goes to see a performance of the sisters, and stops a small fight in the performance. The sisters start to think about the way to get rid of the annoying matters that may cause problems to them someday. Ryuubi's party leaves to continue the journey.
