On 3 October, WACTOR's Twitter account announced auditions for two new members for Mirais and four new members for a sister unit. Over the following days, WACTOR introduced five of their new talents: Mihana Rio, Komori Aina, Tsukito Hana and Mashiro Yuyu, who would form the new sister unit; Kogure Piyoko, who would join Mirais, and an unknown silhouette, who would be later revealed to be Mitsurugi Lia.

After it was found that one of the many IPs involved belonged to a former employee, on 12 March Komori Aina's and Mashiro Yuyu's contracts were cancelled, and Mirais and its sister unit were merged into one group simply called "WACTOR."
