My OC is a girl named Shuriken. She comes from a clan in the Leaf village that I haven't thought of a proper name for yet, but in my head I call it the Tutsaki clan, because I like the sound of it. I don't think it means anything, though.
They have a tradition of being named after weapons, hence her brother being called Kunai and her cousin being called Katana. Ironically, Shuriken doesn't tend to use throwing stars, but instead fights with her boomerang and her kekkei genkai.
The Tutsaki clan's kekkei genkai is otherwise known as the 'blue phoenix jutst'. It allows them to turn their chakra into blue flames that sprout out of their arms. Eventually, when a Tutsaki hones his/her skills enough, they are able to fly. I kind of imagine them to look like blue glowing versions of Howl from Howl's Moving Castle when he partially transforms into a bird.
Shuriken, after much training, eventually develops the jutsu. She spins around in the air and ends up looking like a cathrine wheel. If a shinobi comes into contact with her when she is doing this, they'll probably die in a messy way.
Shuriken's parents died when she was very young. I'd say she was about... five years old. She and Kunai were then taken in by their grandparents. Kunai made her a boomerang.
When she graduated as a ninja, Kunai ended up becoming her sensei! The other two members of her squad were boys who... I haven't really developed in my brain, yet. Sorry. XP
