When you see Ruelle bouncing or running through the city, you will always see her with her trademark smirk on her face and her head raised high. She is straightforward and very confident. Some would describe her as the kind of person that would kick someone into the water to teach them how to swim. She is very energetic and usually the first of her other teammembers that you hear, since she always has something to say. Like her Kwami she loves to be sarcastic or to make bad puns, even when they are facing and enemy. Even in unfamiliar situations or with strangers she is very open , sociable and extroverted. She dearly loves being Ruelle, since her civilian self would NEVER do the things she does as Ruelle. She would have never met the awesome persons she knows because of being Ruelle, and would have never experienced several awesome adventures. She fights without using a weapon and has more of an "brawler" fighting style. Her resistance is very high and her special enchanted gloves are protecting her from taking to much damage when she stops an attack with them. When she is focused on one target she gets a lot faster and stronger, her punches will really hurt if she hits someone. When several people attack her, that isnt the case anymore since she can't focuse one special target anymore. Ruelle is more of an strategist, she can see openings others wouldn't see in the middle of an fight and can shout instructions to several people, while fighting on her own. She is very protective of her teammates and tends to put their well being above those of everyone else. This often leads to situations where she has to decide between protecting her teammembers or civilians, she still has to internalize that her teammates can very well protect themselves.

She hates it when there are no Akuma attacks for a longer period of time since she loves to fight alongside her team. They always tell her to relax, because fighting everyday wont do her any good, but she just dismisses that. For her it means being part of a team, being the leader and to do something for the people of her city. When there are no Akuma attacks she tends to patroul the city when she has time, simply because she wants to hang out with the others and because she can't stand her civilian self for longer than 24 hours at a time. She doesn't know who her other teammates are, so she can't meet them in her civilian form. She would never tell them who she really is because she thinks that nobody could like her normals self, when even she can't seem to like herself.

Ka'ani is the Kwami that lends Mahina her powers and allows her to transform into Ruelle. Ka'ani is a red wolf and the Kwami of leadership. Her favourite food is raspberries, she would literally die for them. She tends to make a mess while eating them and always shows her teeth afterwards, so it looks like she is a small but vicious Kwami that just ate someones innards. Ruelle's good traits partly come from her character, so she is also very courageous (tends to bring herself in danger tho), very open about what she thinks and is the opinion that nobody is better at making (bad) puns than her. She likes to act like she hates everyone, but secretly she likes a lot of people. She doesn't show that tho.
