Elise is the younger sister of Anne Littstein as well as the Mia Luna Tearmoon's Court Artist.

Due to often being sickly and often being in her bed, Elise spent most of her time writing, with one such story being "The Poor Prince and the Golden Dragon", a story that Anne told to Mia in the original timeline while the ladder was held in the dungeon prior to her execution. During it was time, Mia learnt that Elise passed away due to the plague and famine that occurred, and was unable to complete the story.

In the present timeline, Elise has become Mia's Court Artist, a position she original declined assuming she was only being given it due to her sister, but was quickly corrected on by Mia, who accurately guessed (knew from the future) the unwritten parts of her story. She has also grown to be more active thanks to the money Anne sends her family from her pay as Mia's personal maid.

Along side writing "The Poor Prince and the Golden Dragon", Elise she has also written the mostly overexaggerated and fictional biography "The Princess Chronicles of Saint Mia", as well as the unnaturally accurate to the original timeline story "Guillotine Princess", which Anne enjoys the most and likes to refer to as Guillopuri.
