Yostar (Arknights, Azur Lane) has announced its upcoming RPG "Blue Archive" is scheduled to release later this year! Formerly known as "Project MX," Blue Archive is being developed by Korean studio "NAT Games," a subsidiary of Nexon Korea! So one can expect this to be a very high-quality game.
There are no gameplay footage or screenshots yet, but the premise so far is that players will be playing a role of a "teacher" who will "lead students to solve a variety of incidents that occur in the city."
CBT registration for the game is now available until the 31st of July for only 2000 participants in Japan with Android devices. An iOS CBT will likely be coming soon afterward.
