Not being able to see, she then hears a voice saying that she will be staying there for eternity and he starts to remember all the evil she has done. She finds that her arms are in red handcuffs, like the red of bloodshed, and her ankles are in blue shackles, like the blue of tears shed. Erratic hears a "Lu li la" melody of someone's voice coming from somewhere and is slowly healing her soul, though she wonders who it is singing the melody.

An unspecified amount of time passes, and one day, Erratic recognizes the meaning of the lullaby being sung as well as adds new words to it.
