More of an attempt to make the main character of Anomalous Coffee Machine (in human form) than to duplicate the game's style. Main prompt is "ACM1", along with "short hair,multicolored hair,black hair,purple hair", with "long sleeves,jacket,skirt" for her clothes.
Use "Monochrome" to get close to the games style and negative prompts if you don't want the naughty stuff.
