When Akari talkes about her dress, she kind of reminds me of Aira Harune (From Pretty Rhythm).
She got a new dress-fever dress which is going to be the new concept in this season. Also the appeal is called “Fever appeal“ :)
A new update is that a new pop brand is coming out, which is called Mecha PaniQ usted by a new character called Nina Dōjima.
