Hikaru Mikasa
aka Snowy Knight
A little yukki onna girl that Tamono, Minako, and Makoto found in the snowy forest of Tokyo during the "Dark Veil" incident.
Hikaru is 11 years old, she lost her parents and village due to a "witch" casting a terrible spell that buried the village in a snow storm and froze it's denizens to death. However, the reality is that she did it while under stress the villagers put her through. While crying about the "witch" nightmare she had, she unconsciously caused a snow storm that destroyed her parents and home.
Wandering alone and living by herself in her run down home she managed to dig up, she was always in fear of the "witch" and blamed her for it. Tamono, after arriving, explained to her that SHE was the "witch" and that she caused the blizzard. Shocked and devastated, she cried wanting her mommy and daddy who were dead. Tamono braved the storm she created, singing a lullaby she always sung to her children, San and Katsumi, when they were younger, and embraced her.
After a heart-felt conversation, she decided to adopt Hikaru. Hikaru has an admiration for her new brother and sister, but even has a bigger admiration for Rei, who is sailor mars, despite the conflicting elements. She wanted to be like them, so she became a knight for queen serenity.
Being a yukki onna, she can create massive ice attacks and projectiles. Freezing the landscape is simple for her, however she has a low heat tolerance and her body is always ice cold. To counter this, the Vulepkin, a fox people race, scientists have made her her own body suit that keeps her icy body temperature to herself, making her approachable, and protects her from heat.
Shes a chipper and happy girl most of the time, especially when around her idols. She helped combat the demons in the "dark veil" incident, and protected Rei from Lazer fire when the space pirates crashed into town and resisted apprehension.
