louise_(midboss)_(touhou)
Louise as she appears when she's the midboss of Stage 4 of Mystic Square, she has red eyes and blue hair with a blue bow. Her dress's color is also changed accordingly, and it has red edges on the skirt. She also seems to have a ghostly aura around her. Some fans think of her as a separate character from Louise due to her having no dialogue.
