Kinu has an innocent and cheerful personality, one that has never seen danger. She is very active and loves to play with others, especially her father. Cheerful, upbeat and generally a friendly girl, she has a tendency to become overly jealous and possessive when it comes to Nishiki. As he is the only fox that she knows, and being her father, she is extremely concerned when it comes to him. Deep down, she just wants him to be happy and will give him space when he needs it.

Ever curious about the origins of the Youko, she begs her father to take her to the Youko Village. However, Nishiki feels that she isn't old enough yet for the journy, nor does she have the experience to make it. Upset with his decision, she takes off to find the village herself, to the distress of her father when he realizes what she's done. He immediately chases after her, and is surprised that she was actually coming back. With their reunion, he promises that after the war is over, he'll bring her there himself. He also promises that she'll have lots of friends, since he's the village chief.

During her time in the war, she has become a valuable friend to Nohrian, and Hoshidan alike and is often seen mingling with just about anyone. She does not seem to care that Nohr is her 'enemy' and only see's others as potential playmates. This generally annoys the Hoshidan members, especially when she's trying to play with them. She's often turned down or scolded, but it's later revealed that all her playing around and games are the way that she trains herself. A means of growing stronger, and not just because she's childish.

She has inherited a deep thirst from her father, as well as the urge to groom her tail to meticulous standards. She often boasts that she brushes it one-hundred times in the morning, and one-hundred times before bed. Another random quirk that she has is the tendency to run away, sometimes for days at a time with no warning. She does eventually wander back to camp, acting like nothing happened. No one knows what she's doing when she wanders.

Kinu is a hyperactive child, despite her appearance. She tends to bounce focus on whatever is happening around her. Such as shown in her support with Deere, he asks why she is chasing birds and if she wants to eat them, to which she replies that it's because they're running and that must obviously means she should chase them and would eat them "if she feels like it". However the conversation is quickly dropped as the birds are running away again, and she must catch them. Meeting again later, Kinu asks Deere to play with her because it's fun, but Deere finds it boring. Instead of being discouraged, she plays by herself and ends up jumping off of something and hurting herself. Deere of course takes care of her, and she comes to the conclusion that Deere likes healing people, and so she says "Then I’ll make sure to get hurt a lot so you can fix me up!" She is fearless, and tends to not think about the consequences of her actions, leading her to find amusement in jumping off high objects, even if she ultimately ends up getting harmed. "When I start playing, I kind of get lost in my own world, you know? I usually don’t even notice the little injuries."

Running, jumping, bouncing. These are things that she deems to be fun, and quite often, she tries to get others to spend time with her by playing these energetic sorts of games. Though she also finds fun in things that are dangerous or scary. Such as haunted houses. When she drags Ignis to one, he proclaims that he's actually afraid, and she is genuinely confused, as she has never known fear before. "What’s “scared”? I don’t really know what that is…"(note: the only time she "show's fear" is during her My Room confession where she tells the Avatar that she was "never afraid of anything before", but fears the Avatar never coming back). Being afraid is something completely foreign to her, (Ignis even says he envies this of her) and she finds it very strange when others don't do things because of the fear that holds them back. However, she also likes to say that if others are afraid, she'll protect them from whatever it is they happen to be afraid of. Bugs, ghosts, people in the army dying. She wants to find a way to make sure that no one is scared.

Being a Youko, she claims that she has amazing hunting techniques, and it's something that she's really good at. Sensitive ears, and nose, and good at tracking. She uses these talents to hunt food for the army while she's part of it, but also to make sure that the army isn't ambushed by a surprise attack. She's not perfect though. She sometimes lets her more basic instincts take over, eating food from strangers and at least once, she has been captured, and had to be rescued. She comes to regret her actions, and even berates herself, thinking that she's foolish for honestly believing the poachers. She even comes to think that if she were to be captured again, she'd just make trouble for everyone. (Note: see support with Kisaragi). She has a protective instinct that kicks in when she's around those that she cares about and will not hesitate to use her powers when she needs to, to protect someone in danger. She has a bit of a dark side, shown in her support with the Avata when she gets upset that the Avatar stops her from finishing off an enemy. "Y'know, that guy intended to kill us from the start! Even if he was that badly hurt, so what? If he heals, all he's going to do is come back and try to kill us again!"

She is not without sense. While she loves poultry (claiming that it's low in fat so she can eat as much of it as she wants), she only hunts what she can eat."If you catch too many, then the meat will spoil before you can eat it. And a dead bird can't breed and make more birds, and that's a double waste. So Dad told me to never catch more than I can eat. Otherwise, you upset the balance."Using this as a lesson, the Avatar explains that when one eats too much, they become fat, and thus if they get stained too much with blood, they are nothing more then a butcher. She takes this lesson to heart and changes her tone when it comes to how she fights. She even vows to never take a life needlessly again. (Note: Apparently she does like to cook her meat, and she likes it salty).
