*1: Sin of Wrath-Meliodas.

A woman by the name of Layla Heartfilia one day mysteriously comes across a platinum key with a dragon wrapped around it. He was just taking a walk all around her garden and found it lying in the midst of lillies.

Interested in the key, she took it and began to do research on the cryptic key. Without much knowledge on the platinum instrument, she had no idea of the incantation.

Deciding to take a guess, she held it up and shouted, "Open, Gate of the Dragon!"
