Language Comprehension

This spell allows the user and a target person to understand each other's languages. The extent of this spell is unknown, but it is shown that a human from Earth and a mage from Halkeginia were able to understand each other's speech after being chanted. For instance, Louise de la Vallière inadvertently used this spell on Saito Hiraga while attempting to silence him. As a result, they were able to understand each other; it is unclear which language was their common ground for understanding, but Saito noted that he understood Louise in the Japanese language. However, Louise dismisses this thought.
