Gripen is an Anima. She has a long straight pink hair and violet eyes. She is a small girl with an unknown height but she looks taller than about 5 Foot or 152.4 centimeters. She is depicted as being the same age as Kei but as referenced in episode 5 their age is based on their flight frame or base plane which in those terms she would be 21. When she is not wearing her military uniform (as seen to your right) she most often wears a white dress paired with a tan shorts.
