A story concept
Little disclaimer: This champion has no kit or any of the sorts. All I have is a bunch of lore about her and her relationship with Gnar. (Who is my favorite champion)
Firstly, about her species: Snow Yordles are a race of Yordles that reside in the Freljord. They are quite rare compared to the abundance of the "Bandle Yordles" that can be found just about anywhere. What sets them apart is several factors. Firstly, regardless of gender, Snow Yordles are covered in a thick white down of fur. Also, they are the closest race to Gnar, and as such, still have their tails. Next, they often have blue eyes as well as a strong sense in cryomancy. They enjoy taking baths in the snow (kind of like when you bury yourself in sand) and are relatively quiet. While they do live in the Freljord, they do not partake in the politics there. Snow Yordles often live as small tribes that are scattered around wherever there is snow, with most tribes living in Ashe's kingdom. Even though they are resistant to the cold, and have fur, they still often wear jackets, sweaters, etc, while out in the snow.
Now about the champion herself: Yuki, the Snow Sister.
Appearance: Yuki has white fur, large ears (similar to Gnar's) and light blue eyes. She also has a very large, poofy, white, tail. She wears a pair of black workout pants, a silver winter jacket, and a poro beanie. She is noticeably taller than more female Yordles, and Gnar.
Yuki lives in a tribe just outside Ashe's castle. Like most other Snow Yordles, she doesn't partake in politics. She does, however, like taking care of children. Yuki, despite being relatively young, (Shes in her mid 20s) holds a position as a preschool teacher in Ashe's kingdom. She also will sometimes teach her students a touch of cryomancy. Things changed when Yuki was grocery shopping on a fateful day however. This day, Gnar, who was being accompanied by a summoner, were also present. While what they were doing didn't matter much, by pure accident, the summoner stepped on Gnar's toe. Gnar let out a yelp, and, in a fit of rage accompanied by the pain in his poor toe, he transformed. The summoner ran and raised alarm, telling everyone to flee. However, Yuki did not hear him. She approached Gnar, and told him to quiet down. Gnar loomed over here and let out a fierce roar in her face. Yuki responded by grabbing Gnar's fur, pulling his head to the ground, and snarling right back at him. This was enough to put terror in even Mega Gnar, forcing him to transform back to his small form, leaving behind a suprised, as well as terrified, Mini Gnar. Without a word, Yuki grabbed Gnar by the scruff of his neck, and drug him from the marketplace, all the way to her tribe. Upon arriving, she threw him into the snow, and used her cryomancy to bury him in snow, up to his neck. "You're in time out!" She exclaimed. Gnar immediately went to break from his snow prison, but was met with a slap across his forehead. He reluctantly stayed in his spot as Yuki momentarily left. Gnar suddenly felt a certain comfort from the snow, and soon fell asleep. Gnar jolted awake suddenly, realizing where he was. He then noticed Yuki, who had buried herself up to her neck in snow, right next to him. "It always feels nice, to take a snow bath right after being angry. Don't you agree?" She asked. It was then the summoner that was with Gnar before, arrived to find them in the snow. He demanded that Gnar return with him to the institute of war, however, Gnar refused, and stayed in his snow mound. Yuki reasoned with the summoner, and after a long talk, had him assign Gnar under Yuki's watch. Things started out peaceful, until Gnar was summoned to battle. He refused to fight. Even with his summoner yelling at him through telepathy, he wouldn't budge. That is, until he heard Yuki's voice in his head, telling him to do his best. From then on, Yuki raised Gnar, and taught him to act civilized, and after some persuasion from another summoner, decided to occasionally join Gnar on Summoner's Rift.
** Various quotes:**
"Everyone could use a big sister." "This calls for a snow bath." "Hey! Don't touch the tail. He likes to use it as a pillow." "You look troubled." "Have a hug!" "It's not fun to be lonely. Let me join you, we can be lonely together." "Want to build a snow man?" "Just let your troubles go." "These ears let me hear when someone needs a hand."
By the way, when she is in proximity to another Yordle and does her joke, she will hug that yordle.
