Sailor Mercury, Sailor Senshi, Sailor Moon

A woman dressed in a Sailor Senshi costume, specifically Sailor Mercury. She has short blue hair and is wearing a white sailor-style top with blue accents, a blue skirt, blue boots, and a blue bow on her chest. The costume appears to be made of shiny material, possibly satin or silk. The woman's pose suggests she is standing in front of an arcade game machine, as indicated by the pixelated screen behind her. The background is dark, with red lights visible on the walls and floor, creating a lively atmosphere reminiscent of an anime convention or cosplay event.
