I Spy a Tiny Witch Pri!
On their way home from school, the girls run into their classmate Natsume Mahiru and her little sister Manatsu. At close glance, Manatsu looks kinda like a witch. It turns out, they are going to be participating in the costume festival. Everyone dresses up how they want and parades through the Hanasaki District. Of course, Manatsu is going as a witch. Mahiru is going dressed as her favorite, a vampire. Hearing this, Ringo and the others decide to join in since it sounds fun. However, Mahiru is not very good at making costumes. Ringo proposes that they all make the costumes together while learning from Leila, who is good at sewing. They all gather at Leila's house and get to work making costumes. Source: crunchyroll

Spellbound! Magical Princess Lilpri
The Fairytale World is in trouble. Its princesses and their respective worlds are disappearing, causing a ripple effect in the human world where their stories are popular. In order to save the Fairytale World, the Queen sends three magic animals, Sei, Dai, and Ryoku, to the human world with magic gems to find three girls who can become the "Super Miracle Idols," the princesses Snow White, Cinderella, and Kaguya-hime. Those "princesses" end up being three little girls: Yukimori Ringo, Takashiro Layla, and Sasahara Natsuki. But the gems transform them into older singing superstars, and after their accidental debut at the singer Wish's concert, they become known as "Little Princesses," or "LilPri." Now they must collect Happiness Tones from humans in order to restore the Fairytale World.
