Hatsune Miku will be available as a limited gacha character in Blue Archive, for the duration of her event period post the 3 November 2021 maintenance to the 17 November 2021 pre-maintenance. Any interested fans will want to save up enough for 200 pulls to guarantee themselves the digital diva. She’s classified as a backline support unit, casually singing as bullets fly her way.
The event will include a rhythm mini game of sorts, with the regular slew of missions you can do to earn premium currency. There will be auto play offered so that you can watch Miku do her thing, though the announcement does mention your score will not be saved if you do so.
Presumably, the global release should be able to get this collab without issue sometime in the future, though of course, the schedule will be up to Nexon to decide. The program director mentioned that the schedule may be changed, after all.
