Trivia

 * Like Under Night In-Birth characters, this marks the first time Akatsuki/En-Eins characters, alongside Arcana Heart characters, have received English dubs.
 * This is also technically the first time Senran Kagura characters have received English dubs in a video game (while the first English dub of the series was in its anime adaptation). However, should another batch of DLC characters from the series be announced, some Senran Kagura fighters (particularly those whose names have already been datamined) will likely have different English dub actors from those in the anime adaptation.
 * Announcer voice clips for Sai, Fritz, Kanae, Dawei, Adler, Murakumo Zero (to avoid being mistaken for a character from Senran Kagura), Mycale (Perfecti), En-Eins and Kati were found in the version 1.5 ROM through datamining. This may be a hint of further Akatsuki En-Eins character DLCs, however it is not known whether some or all of those characters will actually be playable along with the rest who were datamined as well.
