Nebula Academy (ネビュラーアキャデミー Nebyurā Akademī) is an all girls idol training academy located in Tokyo, Japan in the Chiba Prefecture at Chiba City. The current headmistress is Chinatsu Tachibana. It is a famous, prestigious, and technologically advanced academy, and rival school of Shooting Star Academy. It has grades from beginning of middle school to the end of high school (6th-12th grades). The academy's ace idols and top idols stay and are produced in Top Nebula Office.


Nebula Academy offers multiple courses to the students and they are allowed to add courses at any time, but they are not allowed to switch courses unless they write a request form and the headmistress accepts it.

Idol Course

Most students take this course, but some also add other courses with it. This course trains students who want to become idols by letting them use the various systems and Aikatsu! cards to participate in concerts, auditions and other events.

Designer Course

This course trains the next generation of brand designers. They can promote their own brand themselves if they take the idol course or get a student in the idol course to promote their brand for them in a partnership.

Producer Course

This course trains producers who will produce idols. They can either produce themselves if they take the idol course or they can be paired up with a student taking the idol course to produce them.

Talent Course

This course train idols to do modeling, acting, voice acting, PRs, etc.


There are three main opportunities throughout the year to enroll in Nebula Academy. There are three types of auditions that the academy has:

  • Entry Audition: The entry audition is held every spring after Vernal Equinox Day to determine the years' new students. It consists of a 75 question written exam and a live audition. To pass, the idols are judged by the headmistress, a representative model, and a top idol; idols are judged based on their ability to sing, ability to dance, their potential, and whether they fit the academy's image. The idols can choose whether to create their own good coords or select coords from a book of cards that the staff of Nebula Academy has chosen.
  • Transfer Audition: The transfer audition is held four times a year; it is held once in the spring on the second Monday of March, once in the summer, and twice in the fall/autumn. It is open for students who want to transfer from other schools to Nebula Academy. The idols are judged based on their ability to sing, ability to dance, their potential, their good coord creation skills, and whether they fit the academy's image. Like the entry audition, the transfer audition consists of a 75 question written exam and a live audition. The idols are judged by the headmistress, a representative model, and a top idol.
  • Caravan Audition: The caravan audition is the rarest and the hardest to pass. It takes place once every two years and Nebula Academy drives a caravan from town to town, holding auditions. What makes this audition hard to pass is that only one participant--sometimes two, but this is very rare--will get accepted into the academy at every stop the caravan makes. The audition is judged by a representative model, a senior idol, and a top idol.
