Jewelpet Twinkle☆ (Japanese: ジュエルペット てぃんくる☆, Hepburn: Juerupetto Tinkuru☆) is the second Jewelpet anime series created by Sanrio and Sega and animated by Studio Comet, announced in Shogakukan’s Pucchigumi magazine and directed by Takashi Yamamoto. The series first aired on April 3, 2010 to April 2, 2011 on TV Tokyo and TV Osaka. The series premiered later in Spain as part of the Boing programming block. Jewelpet Twinkle is the first series to have critical appeal outside the series’ target demographic, particularly in the doujin community due to the character designs and series’s story plot.
The Second series focuses on Akari Sakura who first met Ruby on the beach on her way to school. At first, Akari can’t understand her due to her Jewel Land Language, but Ruby eats a special candy so she can speak and understand human language. As the day passes, Ruby knows about her problems in school and later apologized, saying that she didn’t know Akari’s personal problems as she tries to cheer her up. As Akari accepts Ruby, a Jewel Charm appears on her hand and she realizes that she was chosen by Ruby to be her partner. After that, she decides to become a student in Jewel Land along with Ruby as they are aiming to collect 12 Jewel Stones get into the Jewel Star Grand Prix. The prize is that three of any wish they want will be granted. As the series progresses, the two learned more about being together as partners and the mysteries surrounding the Twins: Yuma and Alma and the connection to the forbidden item, the Battest.
The series’s music is also composed by famous Video Game Composer Shiro Hamaguchi like the first series. Two songs were made for both the Opening and Ending themes of the series. The Opening theme is titled “Happy☆Twinkle” (Happy☆てぃんくる, Hapii☆Tinkuru) by former AKB48 member Kayano Masuyama featuring Ayaka Saito and Miyuki Sawashiro as both Ruby and Labra. The ending theme is titled “Scribbling at the Sky” (空ニラクガキ, Sora ni Rakugaki) by Natsumi Takamori, Ayana Taketatsu and Azusa Kataoka as Akari, Miria and Sara.
