Ratatoskr (ラタトスク, Ratatosuku) is an organization created for the purpose of saving Spirits, the cause of Spacequakes, through peaceful mean without killing the Spirits. As stated by Kotori, "The organization called <Ratatoskr> was an organization created for Shido's sake."
The organization known as <Ratatoskr> is only known (probably) by the upper level of the government and high-ranking military officials. The <Ratatoskr> Command center is on the airship <Fraxinus>, while their headquarters is located elsewhere (its location is still unstated).

- In Norse mythology, Ratatoskr is a "Drill-Tooth Squirrel" which acts as a messenger that climbs up and down the world tree "Yggdrasil" to which the 9 worlds are anchored.
- Ratatoskr was formed by Elliot Woodman after he left D.E.M. in order to stop Westcott's ambitions.
- In the anime, Ratatoskr seems to be responsible for the creation of many dating sim games in the series. The people playing these dating sims are unaware that they're helping Ratatoskr through them.
- When the Fraxinus needed name ideas when Tohka asked Shido to name her, Hiroto's dating sim game asked for a name idea. He chose the name "Tome" which Tohka disliked greatly, thinking Shido was attempting to make fun of her.
