Zeynep : The story of a young Turkish girl who will become a Masked Rider

I just had the idea to write a chapter, story telling how Zeynep became Masked Rider Valkyrie
I suspect that what I am going to write will be completely different from the series but I don't care

Plot :
Since the death of her mother, Zeynep was raised by her father, Semir, whom she loves and admires more than anything else.
However, Semir is often very busy with his work
Growing up, the young girl didn't always follow the right people and do good things
Now she has the opportunity to use her skills, her abilities to do good.
Will Zeynep be tempted by her "old demons" or will she become the heroine who will assume the Masked Rider Valkyrie's mantle ?
