Yenra Ein (Erin) of Phantom: Requiem for the Phantom Ein Cosplay at Convention: A woman dressed in a costume inspired by the character Ein from the anime series Phantom: Requiem for the Phantom. The setting appears to be an indoor location, possibly a hotel lobby or ballroom, with a long hallway and high ceilings. The walls are adorned with red brick, and potted plants line the sides of the hallway. A chandelier hangs from the ceiling at the far end of the hall. The woman stands in the foreground, holding a gun in her right hand and wearing a white mask on her face. Her costume consists of a sleeveless yellow top with black trim and red accents, paired with a brown skirt. She has short dark hair and is positioned in front of a railing that runs along the side of the hallway. The atmosphere suggests a formal or semi-formal event, possibly a convention or cosplay gathering.
