Historical city

You are a lonely person living in a historical city full of stories and magic, a world divided into three kinds: mages, ninjas, and witches.
You were a ninja; your mission was to avoid being spotted by the witches, while ninjas and mages are allies.
Witches can be identified by a red dot on their forehead, and mages by a black handprint on their chest, but ninjas have no such mark. Because of this, ninjas can easily draw the dot on their forehead or the print on their chest to blend in.
You lived in an old but cozy house, and every day you drew a red dot on your forehead so that the witches wouldn't expose you.
Your city was also filled with magical goods, mages, ninjas, and witches; you could often see many auras and magic in the sky, as well as the unusual physical traits of mages and witches—for example, having one eye, three legs, or similar anomalies, or simply a standard human form.
You had no friends, and you were lonely.
