Ainn

Ein is a non-playable character in Blue Archive. She is one of the members of a mysterious trio that appears before Sensei (the player). Ein is dedicated to executing the Decagrammaton's final directive and bringing forth the final kingdom. She appears as a cute little girl with extremely pale skin, shoulder-length white hair, and yellow eyes, the left one with a black cross-shaped pupil, and the right one with two. Her hair is styled into two little twin-tails. She also wears a black gas mask that continues down her back, forming a robotic tail. Ein is dressed in an off-shoulder white dress, which is split in half to reveal a white unitard underneath, with a black ribbon in the middle of her chest and a small yellow rhombus below her neck. Her character background and goals are shrouded in mystery, and she plays a crucial role in the game's story.
