Seira Otoshiro (音城セイラ Otoshiro Seira) is one of the main characters debuting in the Data Carddass Aikatsu! 2014 Series and Season 2 of the related anime adaption, representing Dream Academy. She is a rock-genre character and a cool-type Aikatsu idol. Her primary card brand is Swing Rock.
Seira has pink hair, which reaches up to her waist and is tied up into a ponytail. Her eyes are orange and she sports a purple ribbon on her ponytail. Before her debut, she wore her hair down until Ki tied it up.
Seira is a leader type who loves rock. She comes off as confident and bold, but she's actually pretty shy and very humble. She is often seen giving Kii Brain Thunder when she is researching and/or collecting data. She loves cats and is sometimes seen playing her guitar.
In the past, Seira played classical instruments but moved on to rock when she first played the guitar. Similar to Ichigo, her family owns a cafe: Cafe Vivo. She was part of a rock band before becoming an idol. Her sister, Noel, was watching a Soleil show when Seira arrived from playing with her band she was inspired by how idols were able to create smiles among the crowd and decided to try to enter Starlight Academy, however she was rejected as the judges thought she fitted more as a rock singer than an idol. After the disappointing result, she came across the Dream Academy news on a magazine and demanded for an entrance opportunity at their gates. Tiara Yumesaki saw Seira´s passion for music and her idol activities began as a student at the newly opened academy. Her dream is to create beautiful music that would make people smile as well as make her sister happy from the bottom of her heart.
