Maeno Aki is a young adult of short stature with red hair and light red eyes. His hair is disheveled and accompanied by uneven bangs, the lengthier side of which is constantly kept in a braid. He usually is seen wearing a white T-shirt that slips down his left shoulder along with red-and-black striped sleeves which are not connected to any other article of clothing. Black trousers with red lining and red sandals complete the look. In the Sin Branch as well as the recollection flashbacks.
