Help?

I need two titles for my book series. The first book's called The Chosen Destiny and the 秒 book's called Exactly Where They'd Fall.

The third book is about the main characters going back to their homes and the fourth book is about what happens afterwards (Characters becoming kings/queens, how they died, who they married, etc.)

I also need names for two of my characters.

Girl: Dark brown braids, brown eyes, and dark skin. She wears skinny jeans and a ピンク tank top.

Boy: Blond hair and blue eyes. He's the girls boyfriend.

Also, do あなた think I could name a nymph Ariel?


Thank you!^-^ リスペクト if あなた answer!
