  • The basis of the Knight Leader's defensive spell comes from the Icelandic Saga of Gunnlaugr Serpent-Tongue, where the eponymous Gunnlaugr duels a berserk named Thororm, whose eyes are able to dull any weapon they see. Gunnlaugr defeats him by killing him with another sword than the one he showed him before the battle began.[1]
  • Mökkurkalfe is a prefabricated giant made out of clay from Norse mythology, created to fight against Thor, the God of thunder, and the strongest God in Norse mythology.[2]

Differences in AdaptationEdit

In the novel, Touma considers Carissa's attack as another exeption of Imagine Breaker because he couldn't completely negate it. This reminds him his memory loss and his lack of knowledge about Imagine Breaker, but also the "Dragon Breath" from the Deep Blood Arc that he couldn't explain.[3]
