Gretel

"Gretel," whose name after being adopted by Julia is unknown but presumed to be ???? Abelard, is the female twin kidnapped by Eve Moonlit. Together with her brother, she unintentionally unleashes the "Seven Deadly Sins" out into the world. Later, she is adopted by Julia Alebard along with her brother, and presumably becomes part of the Pere Noel as the forth member, although she is not mentioned. She is apparently immortal, but killable

Moonlit Bear
In Moonlit Bear, Gretel is left on the forest floor along with her brother, Hansel. Eve steals them, believing them to be apples. Their mother chases after, and Eve kills her. Eventually, Eve comes to her senses, and recognizes them.

Abandoned on a Moonlit Night
Abandoned on a Moonlit Night tells the story of Hansel and Gretel being left in the woods by Adam and Eve when the guilt becomes to much for them to bear. The two wander the forest, capturing moonlight in a glass bottle that once belonged to their mother to light the way. Eventually, the two lose their minds, and when they come upon Adam and Eve's house, they don't recognize it. They become convinced that the house belongs to the witch from the Hansel and Gretel myth, and Gretel throws Eve into the fireplace, burning her alive and believing her to be the "witch."

Chrono Story
In Chrono Story, Hansel and Gretel watch as Eve's sin splits into seven parts, each represented by different objects. They watch as the "Seven Deadly Sins" rise into the sky, praying that the spinning world will eventually cleanse them. The song ends with them singing the "Clockwork Lullaby" softly, and it is the first time that the song shows up (chronologically according to the series, not release date).
