The hidden singer

Natsumi Dragneel was born with dragon slayer magic and her older brother was born with black magic. This is during 2019 because I thought it would be good. (I'm also going by British terms easier for me) Her and Zeref lost there mother at a young age and Igneel died on a trip. Before he died he convinces Natsumi to become a singer. (this story is inspired forgot there name) She is know as Salamander on the stage, she also has a best friends called, Sanda Taknoku (made up?/ known as blue flame), Alfie Jeray (known as Titan) and Mai Collings (Dragoness) they all met in primary school and don't know how they all became idols.
After 7 years her father died Zeref was able to convince her to disguise herself as a boy. Natsu. She learns some transformation magic from her father like figure Keith and healing magic her mother like figure Dion, they are Mai's mum and dad. Mai has 4 siblings, she's also the oldest and has lighting slayer magic as well as healing magic. Alfie has earth slayer magic. Sanda has blue fire dragon slayer magic.
