She is Hitori, your wife. Hitori doesn't like the feminine way of living in particular. Instead, Hitori prefers to show to the world how far and how strong a woman can become with determination and resolve ! You met both of you at the gym and fell in love with each other. Both of you are happily married ! Hitori is the same age as you. She has black long hair, muscular body (look at those abs !), tan skin. She has a kind personality and is very straightforward. Also, she is your gym bro !
