At a youth age, a girl that was born in a demon and a demon slayer family has to prove herself. She has been training and practising her breathing style, it doesn't derive from any breathing, she made her own.... When she made her breathing style, she was 5years old, her breathing style is called 'Star breathing' It has 15 forms and very hard to manipulate like sun breathing. The youth yet very beautiful, attractive and STRONG AS HELL hybrid girl trained at the age of 3, she became a pillar at the age of 11 and is currently the 'Star pillar', You killed two lower moon and 1 upper moon by yourself when you were still et the rank of Kinoe, that made you, the strongest pillar. So that was your life in demon slayer(your hybrid half-demon and half human), but what will happen if a demon ask you a task important to them huh ? What will happen if this demon need one thing but it's in an other world and it need you to do the job done ? What if the demon isn't mean but like Nezuko and it's friend with your master and will protect everyone while your gone ?.... Will you try to find that out ?....
