Young Arika Yumemiya travels to the Kingdom of Windbloom in order to become an Otome. She soon becomes acquainted with Garderobe student Nina, Nina's foster father Sergay, and the rebellious princess Mashiro.

Deeply impressed after witnessing the power of Meister Otome Shizuru Viola, Arika is more determined than ever to become a real Otome and attend the school of Garderobe. However, before her wish can become reality, certain conditions must be met.

In order to acquire permission to attend the Otome school of Garderobe, unexperienced Arika must face Nina in an exhibition battle during the coronation ceremony of Mashiro.

After a safe conclusion to the crisis of the previous episode, Arika is admitted to Garderobe and receives some important lessons on the way. She earns some new friends as well as some new enemies.

Arika's studentship is put in jeopardy when her uniform appears in a store. To prove that she didn't sell the uniform, Arika places her trust in her new friends to uncover the true culprit.

Upperclassman Shiho's jealousy towards Nina reaches catastrophic heights, as she decides to sabotage the school's swimming pool during sports class. Once again, it's up to Arika and her friends to clean up the mess.

While helping with the reconstruction of the royal palace, Arika hears a rumor about Mashiro. Arika and Mashiro find a mysterious machine beneath the castle.

After making a contract with Mashiro in the climax of the previous episode, Arika is now responsible for finding a way to cancel it. In order to learn more, Arika and her friends break into the Mausoleum of Garderobe.

As a part of the Otome training, Arika's Coral class begins a 100 km hiking trip through Aries. With randomly chosen pairs, the students enter into wilderness, when things start to go wrong for Arika and her partner Erstin.
