The guardians of the universe, created Leila, Leilia and Lorelei to help protect the universe. Heartless' called a freak and (pls don't judge me but yes I like sonic.exe games) she only appeared in my sonic.exe story. Heartless is the destruction of the universe and then there's Heartful her opposite. Heartful is the life of the universe and yes they created Leila and Leilia to carry out Heartful and Heartless' duties and the destruction and life of the universe but as both girls got completely different powers. Leila got time and space, and Leilia got death. So Heartful made Lorelei to stop both in the middle of battle, as Lorelei is a music loving girl, she was given the ability to save anything using her singing. Heartless is the one with no eyes and Heartful is the one that has blue eyes and is as white as a snowflake.
